Forgone healthcare and intimate partner violence : A study in six European urban centres
- 2014
-
Conference paper (peer-reviewed)abstract
- Background: Victims of intimate partner violence (IPV) are known to refrain from seeking care when in need. Whether the impact on forgone care differs according to the victim-perpetrator role remains unexplored. We aimed to describe the relation between past-year IPV and forgone healthcare according to victims, perpetrators or both (bidirectional). Methods: Adult men and women (n=3496, aged 18-64), randomly sampled from the general population of Athens, Porto, London, Budapest, Östersund and Stuttgart were assessed using a common questionnaire. IPV was ascertained with the Revised-Conflict-Tactics-Scales. The association between IPV and forgone healthcare (“Have you been in need of a certain care service in the past year, but did not seek any help?”), sociodemographics (sex, age, education, city) and health factors (self-assessed health, public or private healthcare sector use), in victims, perpetrators and both was estimated using adjusted logistic regression odds ratios (AOR, 95% confidence intervals). Results: Forgone healthcare ranged from 12.6% (Budapest) to 22.4% (Stuttgart) and was associated with bidirectional involvement in IPV (AOR, 95%CI= 1.37, 1.05-1.78). A lower educational level was associated with forgone care in multivariate models fitted for victims of and for bidirectional involvement in IPV. A fair/poor self-assessed health (contrasting to a good/very good/excellent health) was significantly associated with forgone care in victims (AOR, 95%CI=2.61, 1.96-3.47), in bidirectional IPV (AOR, 95%CI=2.94, 2.27-3.82) and for perpetrators (AOR, 95%CI=2.58, 1.96-3.40). Conclusion: Beside the known barriers identified for inequalities and access to healthcare, the role of IPV in forgone healthcare should be considered.

Journal article (peer-reviewed)abstract
- Objective To describe the design, methods, procedures and characteristics of the population involved in a study designed to compare Intimate Partner Violence (IPV) in eight European countries.Methods Women and men aged 18–65, living in Ghent-Belgium (n = 245), Stuttgart-Germany (n = 546), Athens-Greece (n = 548), Budapest-Hungary (n = 604), Porto-Portugal (n = 635), Granada-Spain (n = 138), Östersund-Sweden (n = 592), London-United Kingdom (n = 571), were sampled and administered a common questionnaire. Chi-square goodness of fit and five-age strata population fractions ratios for sex and education were computed to evaluate samples' representativeness.Results Differences in the age distributions were found among women from Sweden and Portugal and among men from Belgium, Hungary, Portugal and Sweden. Over-recruitment of more educated respondents was noted in all sites.Conclusion The use of a common research protocol with the same structured questionnaire is likely to provide accurate estimates of the general population IPV frequency, despite limitations in probabilistic sampling and restrictions in methods of administration.

Interaction of forsterite-91 with distilled water and artificial seawater : a prebiotic chemistry experiment
- 2013
-
In: International Journal of Astrobiology. - 1473-5504 .- 1475-3006. ; 12:2, s. 135-143
-
Journal article (peer-reviewed)abstract
- In the present work, the interactions between forsterite-91 with distilled water and forsterite-91 with artificial seawater were studied at two pHs (2.0 and 8.0) using different techniques. A large increase in pH was observed for samples incubated at an initially acidic pH (2.0) due to the dissolution of forsterite-91 in distilled water and artificial seawater. Thus, in acidic hydrothermal vents, an increase in the amount of hydrocarbons and magnetite should be expected due to the release of Fe(II). The pH(PZC) decreased and the pH(IEP) increased when forsterite-91 was treated with distilled water and artificial seawater. The ions from the artificial seawater had an effect on zeta potential. Scanning electron microscopy (SEM) images and X-ray diffractograms showed halite in the samples of forsterite-91 mixed with artificial seawater. The presence of halite or adsorption of ions on the surface of forsterite-91 could affect the synthesis of magnetite and hydrocarbons in hydrothermal vents, due to a decrease in the dissolution rates of forsterite-91. The dissolution of forsterite-91 yields low concentrations of Fe(III) and Mn(II) as detected by electron paramagnetic resonance (EPR) spectroscopy. Microanalysis of forsterite-91 showed a higher amount of Mn, with an oxidation that was likely not + II, as Mn in supernatant solutions was only detected by EPR spectroscopy after mixing with artificial seawater at pH 2.0. As Fe(III) and Mn(II) are catalyst constituents of magnetite and manganese oxide, respectively, their presence is important for synthesis in hydrothermal vents. Etch pits were observed only in the forsterite-91 sample mixed with distilled water at pH 8.0. Na, Cl, S, Ca and K were detected in the samples mixed with artificial seawater by SEM-EDS. Si, Mg, Fe and Al were detected in almost all supernatant samples due to forsterite-91 dissolution. Cr was not dissolved in the experiments, thus Cr in the mineral could serve as an effective catalyst for Fischer Tropsch Types (FTT) reactions in hydrothermal vent systems. X-ray diffractograms of the original forsterite-91 also showed peaks arising from zeolites and clinochlore. After the samples were treated with artificial seawater, X-ray diffractograms showed the dissolution of zeolite. Experiments should be performed in the natural environment to verify the potential for zeolites to act as a catalyst in hydrothermal vents.

An exploratory survey of diagnostic methods for bone quality assessment used by Brazilian dental implant specialists
- 2010

In: Journal of Oral Rehabilitation. - : Wiley. - 1365-2842 .- 0305-182X. ; 37:9, s. 698-703

Journal article (peer-reviewed)abstract
- Bone quality (BQ) has been described as an important predictor for the outcome of dental implant treatment. It is, however, unclear how this factor is assessed in the dental practice routine. The aim of this study was to investigate what Brazilian dental implant specialists know and understand about BQ, if they include BQ assessments in their treatment planning and which methods they use to assess BQ. A questionnaire was posted to Brazilian dental implant specialists, containing open and closed questions about their knowledge and understanding of BQ assessment, and 221 answered the questionnaire. Data were gathered and methods for BQ assessment were grouped using hierarchical cluster analysis. Answers about BQ knowledge and understanding were categorized into quantity of cortical and marrow bone (n = 72), density (n = 55), type of bone (n = 35), bone height (n = 30), bone thickness (n = 27), primary stability (n = 24) and other less common categories. BQ assessment was judged relevant to be considered a selection criterion for implant treatment. Overall frequency analysis showed that methods were roughly divided into usual (n > 170) and unusual methods (n < 9). Cluster analysis grouped BQ assessment methods into four clusters: unusual methods (DEXA, resonance frequency, Periotest and occlusal radiography), perioperative methods (peak insertion torque and tactile perception), sectional imaging (computed tomography) and plain films (periapical and panoramic radiographs). No consensus on BQ understanding or the clinical application of methods to assess BQ was found in this survey. The selection of methods shows a clear natural grouping from basic to advanced strategies for BQ assessment by Brazilian specialists in dental implants.
