Angelica Balabanova, socialiste russe en exil (1900)
No full textAu moment où se situe l’extrait, en 1900, après son périple universitaire, Angelica Balabanova (1878-1965) décide de sauter le pas et de s’engager officiellement dans le Parti socialiste italien. Influencée par bon nombre de ses professeurs, notamment Antonio Labriola, ainsi que par ses lectures de l’Avanti ou encore ses discussions avec des amis socialistes, elle rejoint officiellement le mouvement ouvrier au tout début du xxe siècle. Elle y tient rapidement un rôle majeur. À ce moment-là, ..
Costs and outcomes of tuberculosis control in the Russian Federation: retrospective cohort analysis.
No full textWe analysed costs and outcomes of tuberculosis care for patients in a traditional Russian tuberculosis control system, using 3-year retrospective cohort data. Of 1749 cases at 3 years of follow-up, 65% were cured, 11.3% (198/1749) still had 'active' or 'chronic' disease, 10.3% had transferred out of the local civilian health care system and 12.7% had died. The mean cost of managing one case over 3 years was 886 US dollars: 1,078 US dollars for bacteriologically confirmed (BK+) cases and 718 US dollars for bacteriologically unconfirmed (BK-) cases. Approximately 60% of treatment costs were incurred in the first 12 months and 40% incurred in the remaining 2 years. Around 60% of the total cost was accounted for by hospital inpatient care. The cost, treatment and outcome of BK+ and BK- cases differed substantially. The cost of treating BK+ cases was 50% higher than treating BK- cases due to higher hospitalization rates and the additional cost of managing BK+ cases that become 'chronic'. While BK+ cases accounted for 55% of total health expenditure on tuberculosis, the share of BK- cases was 45% of the total - due to hospitalization and lengthy periods of follow up. The costs of treating tuberculosis in the Russian tuberculosis control system are very high compared with other high-burden countries due to hospitalization policies and lengthy case management periods. Much of this expenditure can be avoided if the WHO-recommended DOTS strategy is implemented. In particular, the proportion of expenditure for BK- cases is surprisingly high and can be avoided as most of these patients do not need hospitalizing or lengthy periods of follow-up

Comparison of rivaroxaban and low molecular weight heparin in the treatment of cancer-associated venous thromboembolism: A Swedish national population-based register study
No full textBackground Treating cancer-associated venous thromboembolism (CAT) with anticoagulation prevents recurrent venous thromboembolism (rVTE), but increases bleeding risk. Objectives To compare incidence of rVTE, major bleeding, and all-cause mortality for rivaroxaban versus low molecular weight heparin (LMWH) in patients with CAT. Methods We developed a cohort study using Swedish national registers 2013–2019. Patients with CAT (venous thromboembolism within 6 months of cancer diagnosis) were included. Those with other indications or with high bleeding risk cancers were excluded (according to guidelines). Follow-up was from index-CAT until outcome, death, emigration, or end of study. Incidence rates (IR) per 1000 person-years with 95% confidence interval (CI) and propensity score overlap-weighted hazard ratios (HRs) for rivaroxaban versus LMWH were estimated. Results We included 283 patients on rivaroxaban and 5181 on LMWH. The IR for rVTE was 68.7 (95% CI 40.0–109.9) for rivaroxaban, compared with 91.6 (95% CI 81.9–102.0) for LMWH, with adjusted HR 0.77 (95% CI 0.43–1.35). The IR for major bleeding was 23.5 (95% CI 8.6–51.1) for rivaroxaban versus 49.2 (95% CI 42.3–56.9) for LMWH, with adjusted HR 0.62 (95% CI 0.26–1.49). The IR for all-cause mortality was 146.8 (95% CI 103.9–201.5) for rivaroxaban and 565.6 (95% CI 541.8–590.2) for LMWH with adjusted HR 0.48 (95% CI 0.34–0.67). Conclusions Rivaroxaban performed similarly to LMWH for patients with CAT for rVTE and major bleeding. An all-cause mortality benefit was observed for rivaroxaban which potentially may be attributed to residual confounding.Fil: Linder, Marie. Karolinska Huddinge Hospital.

An analysis of trends and determinants of health insurance and healthcare utilisation in the Russian population between 2000 and 2004: the 'inverse care law' in action.
No full textBACKGROUND: The break-up of the USSR brought considerable disruption to health services in Russia. The uptake of compulsory health insurance rose rapidly after its introduction in 1993. However, by 2000 coverage was still incomplete, especially amongst the disadvantaged. By this time, however, the state health service had become more stable, and the private sector was growing. This paper describes subsequent trends and determinants of healthcare insurance coverage in Russia, and its relationship with health service utilisation, as well as the role of the private sector. METHODS: Data were from the Russia Longitudinal Monitoring Survey, an annual household panel survey (2000-4) from 38 centres across the Russian Federation. Annual trends in insurance coverage were measured (2000-4). Cross-sectional multivariate analyses of the determinants of health insurance and its relationship with health care utilisation were performed in working-age people (18-59 years) using 2004 data. RESULTS: Between 2000 and 2004, coverage by the compulsory insurance scheme increased from 88% to 94% of adults; however 10% of working-age men remained uninsured. Compulsory health insurance coverage was lower amongst the poor, unemployed, unhealthy and people outside the main cities. The uninsured were less likely to seek medical help for new health problems. 3% of respondents had supplementary (private) insurance, and rising utilisation of private healthcare was greatest amongst the more educated and wealthy. CONCLUSION: Despite high population insurance coverage, a multiply disadvantaged uninsured minority remains, with low utilisation of health services. Universal insurance could therefore increase access, and potentially contribute to reducing avoidable healthcare-related mortality. Meanwhile, the socioeconomically advantaged are turning increasingly to a growing private sector
Spatially-localized time dependent solutions including turbulence and their interactions in 2D Kolmogorov flow
No full textIn 2D Kolmogorov flow in small aspect ratio domains, spatially-localized solutions such as kink, traveling or time-dependent kink-antikink pars coexist. However, the conservation of the flow rate in the y direction strongly restrict combination of localized solutions and their positioning. We find that by adding a homogeneous flow U y their positioning is controlled and each of localized solutions including a spatially-localized chaos is isolated. Numerical results suggest that these isolated solutions can be elements constructing a whole flow
Polaribacter staleyi sp. nov., a polysaccharide-degrading marine bacterium isolated from the red alga Ahnfeltia tobuchiensis
No full textA Gram-stain-negative, rod-shaped, motile by gliding and yellow-pigmented bacterium, designated strain 10Alg 139T, was isolated from the Pacific red alga Ahnfeltiato buchiensis. The phylogenetic analysis based on 16S rRNA gene sequences showed that the novel strain belonged to the genus Polaribacter , a member of the family Flavobacteriaceae , the phylum Bacteroidetes , with highest sequence similarity to Polaribacter butkevichii KMM 3938T (99.3 %) and 93.3–98.6 % to other recognized Polaribacter species. The prevalent fatty acids of strain 10Alg 139T were iso-C15 : 0 3-OH, C15 : 0 3-OH, iso-C15:0, iso-C13 : 0, C15 : 0 and C15 : 1ω6c. The polar lipid profile consisted of the major lipids phosphatidylethanolamine, two unidentified aminolipids and four unidentified lipids. The main respiratory quinone was menaquinone 6. The DNA G+C content of the type strain is 31.8 mol%. The new isolate and the type strains of recognized species of the genus Polaribacter were readily distinguished based on a number of phenotypic characteristics. A combination of the genotypic and phenotypic data showed that the isolate from alga represents a novel species of the genus Polaribacter , for which the name Polaribacter staleyi sp. nov. is proposed. The type strain is 10Alg 139T (=KCTC 52773T=KMM 6729T)
Characteristics of overlap region in high-Reynolds number turbulent channel flow
No full textDirect numerical simulation of the fully developed turbulent channel flows have been carried out at the Reynolds number based on the friction velocity and the channel half width, 2000, 4000 and 8000. A hybrid 10th order accurate finite difference scheme in the stream and spanwise directions, and a second-order scheme in the wall-normal direction is adapted as the spatial discretization method. We observed the plateau profiles in the indicator function corresponded to the von Karman constant. Furthermore, second peak of streamwise pre-multiplied spectra were appeared in the same wall normal height, 300 < y+ < 600, in case of Re = 4000. Nevertheless, the effects of the lager than the channel half height scale on the streamwise turbulent intensity are fixed contributions without dependence on Reynolds number. These results suggested that the new streamwise vortexes are formed between buffer layer and outer layer with increasing of Reynolds number

No full textIn June 2010, the Ortega y Gasset Foundation hosted a Conference about the “Spanish Philosophical Transition” in order to debate the book of Francisco Vázquez, La filosofía española. Herederos y Pretendientes. Una lectura sociológica (1963-1990), recently published. This paper is the author’s response to criticism raised in the Conference and to published reviews received by this book. First, the author summarized the argument of Herederos y pretendientes. Secondly he responds and takes into account the most important objections against the book’s hypothesis and methodology. Finally the author evaluates the favorable judgments received by the book and suggests the limits of the historian’s task.Fundación Ortega y Gasset-Marañó
Author self-citation in orthodontics is associated with author origin and gender.
No full textBACKGROUND
The aims of this bibliometric study were to determine author self-citation trends in high-impact orthodontic literature and to investigate possible association between self-citation and publication characteristics.
METHODS
Six orthodontic journals with the highest impact factor as ranked by 2017 Journal Citation Reports were screened for a full publication year (2018) for original research articles, reviews, and case reports. Eligible articles were scrutinized for article and author characteristics and citation metrics. Univariable and multivariable negative binomial regression was used to examine associations between self-citation incidence and publication characteristics.
RESULTS
Medians for author self-citation rate of the most self-citing authors and self-citations were 3.03% (range 0-50) and 1 (range 0-19), respectively. In the univariable analysis, there was no association between self-citation counts and study type (P = 0.41), article topic (P = 0.61), number of authors (P = 0.62), and rank of authors (P = 0.56). Author origin (P = 0.001), gender (P = 0.001) and journal (P = 0.05) were associated with self-citation counts and in the multivariable analysis only origin and gender remained strong self-citation predictors. Asian authors and females self-cited significantly less often than all other regions and male authors.
CONCLUSIONS
Authors in orthodontics do not self-cite at a frequency that suggests potential citation manipulation. Author origin and gender were the only variables associated with citations counts. More bibliometric research is necessary to draw solid conclusions about author self-citation trends in orthodontic literature
