    A normal phase semi-preparative scale separation of the estradiol analogs 17-\u3c*-propenyl-3 , 17^-estradiol and 17-*-propenyl-^-estradiol-3-acetate was carried out using High Performance Dicplacement Chromatography (HPDC). Two conventional analytical (10 urn, 4.6 x 250 mm, silica) columns were utilized in series for the semi-preparative system. The displacer used was triethanol amine in chloroform, 10% v/v. A total of 169.8 milligrams of the estradiol analogs were separated and collected in their form from the column effluent. The HPDC runs were monitored using thin layer chromatography (silica TLC) . The displacement fractions were analyzed using HPLC in linear elution mode. Carrier and displacer solutions were scouted for using silica TLC. Displacement TLC was used to find the proper concentration of displacer. The migration rates of the displacer solution on the TLC plates were compared to that on the column using HPLC in the frontal mode. HPDC proved suitable for the utilization of conventional analytical HPLC instrumenta tion for a semi-preparative scale separation

    1968 Italian mobilizations were long-lasting, and influenced newly and deeply on behaviours, mentalities, cultures and ways of life. At the same time, state bodies’ violent reaction made evident the limits of a political system whose inability to integrate external stimuli turned out to be a constant feature in republican history. According to this perspective, the present article intends to analyse the reasons, origins, consequences and developments of the Italian “anomaly”, developing political and cultural questions opened by the protests and going over some of its most significant aspects.Los movimientos de 1968 tuvieron en Italia una duración muy larga y una inédita capacidad para influir en lo profundo de comportamientos, mentalidades, culturas y estilos de vida. A la vez, la violenta reacción de los órganos del Estado evidenció los límites de un sistema político cuya incapacidad de integrar los estímulos externos se revelaría como una constante en la historia republicana. El artículo trata de analizar según esta perspectiva las razones, las raíces, las consecuencias y los desarrollos de la “anomalía” italiana, desarrollando las cuestiones políticas y culturales abiertas por la contestación y recorriendo algunas de sus facetas más significativas

    Background To describe trends observed across thirty years in demographic and clinical characteristics and rehabilitation of patients with bilateral cerebral palsy. Methods This retrospective study includes 464 (261 M and 203 F) inpatients with bilateral cerebral palsy, born from 1967 to 1997 and discharged from an outpatient rehabilitative facility from 1985 to 2015. Data concerning the health profile were collected from medical reports and organized in the domains of Body Functions and Structure; Activity and participation and Personal and Environmental factors as proposed in the International Classification of Functioning Disability and Health (ICF). The trend observed over the three birth decades was discussed. Results The duration of the rehabilitative treatment decreased across decades approximately by two years per decade (from an initial 16.2 yrs to 12.3 yrs). Across the decades the rate of quadriplegia decreased, whereas rates of diplegia increased; spasticity was the prevalent observed motor type for all decades. The most frequent musculoskeletal disorder involved the middle inferior part of the body; among comorbidities a steady decrease in psychiatric disorders was found. With respect to the first decade a slight improvement was observed in the gross motor functioning and in the hand dexterity. No particular trend was observed concerning communication abilities. An increase in the use of pharmacological and surgical treatments for motor symptoms was observed. Conclusion This study presents and describes the functioning of a large sample of Italian patients with bilateral CP on the basis of the ICF framework and it discussed the trend observed across decades

    Background This study uses data from the World Health Organization's Study on Global Ageing and Adult Health (SAGE) to examine patterns of hypertension prevalence, awareness, treatment and control for people aged 50 years and over in China, Ghana, India, Mexico, the Russian Federation and South Africa. Methods The SAGE sample comprises of 35 125 people aged 50 years and older, selected randomly. Hypertension was defined as ≥140 mmHg (systolic blood pressure) or ≥90 mmHg (diastolic blood pressure) or by currently taking antihypertensives. Control of hypertension was defined as blood pressure below 140/90 mmHg on treatment. A person was defined as aware if he/she was hypertensive and self-reported the condition. Results Prevalence rates in all countries are broadly comparable to those of developed countries (52.9%; range 32.3% in India to 77.9% in South Africa). Hypertension was associated with overweight/obesity and was more common in women, those in the lowest wealth quintile and in heavy alcohol consumers. Awareness was found to be low for all countries, albeit with substantial national variations (48.3%; range 23.3% in Ghana to 72.1% in the Russian Federation). This was also the case for control (10.2%; range 4.1% in Ghana to 14.1% India) and treatment efficacy (26.3%; range 17.4% in the Russian Federation to 55.2% in India). Awareness was associated with increasing age, being female and being overweight or obese. Effective control of hypertension was more likely in older people, women and in the richest quintile. Obesity was associated with poorer control. Conclusions The high rates of hypertension in low- and middle-income countries are striking. Levels of treatment and control are inadequate despite half those sampled being aware of their condition. Since cardiovascular disease is by far the largest cause of years of life lost in these settings, these findings emphasize the need for new approaches towards control of this major risk facto

    Quality of child healthcare in European countries: common measures across international databases and national agencies

    BACKGROUND: The evaluation of child healthcare is not yet widely explored, especially from a cross-country comparison perspective. The routine adoption of measures by national assessment agencies is under-investigated. Though the guiding principles developed at international level call for a child-centric multi-dimensional evaluation of child care, its feasibility is hampered by the availability of robust and harmonized data. METHODS: To explore the data availability, international databases (IDBs) were scrutinized and measures dealing with child health-related issues were collated. In parallel, an ad hoc questionnaire was administrated to 30 Country Agents (CAs) to gather measures routinely adopted at local level. To facilitate the comparison of measures, a three-level conceptual map was developed. RESULTS: The IDBs yielded at 207 measures that pertained mainly to non-health determinants of health, whereas the 352 measures obtained from CAs focused on process and outcome. A set of 33 common measures that related to immunization, morbidity and mortality were identified. CONCLUSIONS: A limited set of measures used both in IDBs and at national level identify common areas of concerns that certainly capture crucial issues with child prevention and health outcomes. However, they are far from satisfying a child-centric multi-dimensional approach to the evaluation of child well-being and well-becoming. There is room for improvement at both international and national levels. IDBs should include and harmonize measures that concern the provision of child-centric services and encompass physical, social and mental development. At the national level, efforts towards the inclusion of measures that concern non-health determinants of health should be pursued

    Unintentional injuries are one of the main contributors to mortality and disability in elderly populations in low- and middle-income countries. The aim of this study was to examine the annual road traffic and other bodily (not including falls) injury prevalence and associated risk factors among older adults across six lower and upper middle-income countries. A cross- sectional survey involving face-to-face household interviews were conducted in China (n=13,177), Ghana (n=4305), India (n=6560), Mexico (n=2318), the Russian Federation (n=3938) and South Africa (n=3840), resulting in population-based cohorts of persons aged 50+ years.  Measures included questions on injury, self-rated visual difficulties, alcohol use, depression treatment, sleeping problems, self-reported health status, and vision assessment using LogMAR (logarithm of Minimum Angle of Resolution) eye charts. It comprises rows of letters and is used to measure visual acuity. Results indicate that the overall annual non-fatal road traffic injury prevalence was 2.0% and for other bodily injury 2.1% (not including falls) across the six countries. The multivariate logistic regression analysis found that residing in a rural area, taking medications or other treatment for depression in the past 12 months and having a sleeping problem were associated with road traffic injury, while younger age, residing in a rural area, hazardous or harmful alcohol use and having a sleeping problem were associated with other bodily injury. Visual impairment was not associated with prevalence of road traffic injuries. This study provides the burden of non-fatal road traffic injury and other bodily injury and their associated risk factors across the six countries’ studies. The findings of this study improves the understanding of non-fatal road traffic injury and other bodily injury upon which policy makers, programme developers and researchers in public health can design strategic interventions to reduce these preventable injuries as well as improve safety associated with unintentional injuries.Keywords: injury, traffic, ageing, China, Ghana, India, Mexico, Russian Federation, South Africa

    OBJECTIVE —The aim of our study was to examine, in type 2 diabetic patients, the relationship between autoantibodies against oxidatively modified LDL (oxLDL Ab) and two indexes of atherosclerosis, intimal-medial thickness of the common carotid artery (CCA-IMT), which reflects early atherosclerosis, and the ankle-brachial index (ABI), which reflects advanced atherosclerosis. RESEARCH DESIGN AND METHODS —Thirty newly diagnosed type 2 diabetic patients, 30 type 2 diabetic patients with long duration of disease, and 56 control subjects were studied. To detect oxLDL Ab, the ImmunoLisa Anti-oxLDL Antibody ELISA was used. ABI was estimated at rest by strain-gauge plethysmography. Carotid B-mode imaging was performed on a high-resolution imaging system (ATL HDI 5000). RESULTS —In patients with long duration of disease, IgG oxLDL Ab were significantly higher and ABI significantly lower compared with the other two groups. We found a correlation between IgG oxLDL Ab and CCA-IMT in all diabetic patients. A significant inverse correlation between IgG oxLDL Ab and ABI only in patients with long duration of disease was seen, demonstrating a close relationship between these autoantibodies and advanced atherosclerosis. CONCLUSIONS —IgG OxLDL Ab may be markers of the advanced phase of the atherosclerotic process and the response of the immunological system to the oxLDL, which are present within atherosclerotic lesions

    Background: Later years of life are accompanied by many physical, emotional and environmental changes which may impact on the well-being of the individual. Many factors are known to influence the subjectivewell-being of older adults, but most, if not all of this information was the result of studies in the Western world. This study aimed at obtaining and documenting the predictors of subjective well-being (SWB) among older Ghanaians.Methods: Data for the study was obtained from the WHO SAGE study. The single item measure of life satisfaction was used to determine subjective wellbeing. Descriptive statistics as well as logistic regression analysis were carried out to determine the predictors of SWB.Results: A total of 4724 individuals aged 50 years and above responded to the questionnaires. Of these 50.4% were males. Following multivariate logistic regression analysis, age, sex, educational level, income and ethnicbackground were found to significantly affect the SWB of older Ghanaians. Being male was associated with higher level of SWB (OR=1.68; CI: 1.39 – 2.03). For those 50 years and above, being younger (50-59 years) was also associated with a high level of SWB (OR=17.72; CI: 10.13-30.98). Earning a low income and having low educational level were both associatedwith low levels of SWB (OR=0.304; CI: 0.22-0.42; and OR=0.47; CI: 0.37-0.60 respectively). Ewes (p=0.027), Grumas (p=0.002) and  Mole-Dagbons (p=0.04) had significantly higher SWB compared to the other ethnic groups.Conclusion: Among older Ghanaians, factors that positively influence SWB are younger age, male sex, high educational level and high income.Keywords: Subjective well-being, Life satisfaction, Older Ghanaians, SAGE study, Predictor
