Measuring access to medicines: a review of quantitative methods used in household surveys

<p>Abstract</p> <p>Background</p> <p>Medicine access is an important goal of medicine policy; however the evaluation of medicine access is a subject under conceptual and methodological development. The aim of this study was to describe quantitative methodologies to measure medicine access on household level, access expressed as paid or unpaid medicine acquisition.</p> <p>Methods</p> <p>Searches were carried out in electronic databases and health institutional sites; within references from retrieved papers and by contacting authors.</p> <p>Results</p> <p>Nine papers were located. The methodologies of the studies presented differences in the recall period, recruitment of subjects and medicine access characterization.</p> <p>Conclusions</p> <p>The standardization of medicine access indicators and the definition of appropriate recall periods are required to evaluate different medicines and access dimensions, improving studies comparison. Besides, specific keywords must be established to allow future literature reviews about this topic.</p

Angiographically borderline left main coronary artery lesions: correlation of transthoracic doppler echocardiography and intravascular ultrasound: a pilot study

<p>Abstract</p> <p>Background</p> <p>the clinical decision making could be difficult in patients with borderline lesions (visually assessed stenosis severity of 30 to 50%) of the left main coronary artery (LM). The aim of the study was to evaluate the relationship between transthoracic Doppler (TTDE) peak diastolic flow velocity (PDV) and intravascular ultrasound (IVUS) measurements in the assessment of angiographically borderline LM lesions.</p> <p>Methods</p> <p>27 patients (mean age 64 ± 8 years, 21 males) with borderline LM stenosis referred for IVUS examination were included in the study. We performed standard IVUS with minimal lumen area (MLA) and plaque burden (PB) measurement and routine quantitative coronary angiography (QCA) with diameter stenosis (%DS) and area stenosis (%AS) assessment in all. During TTDE, resting PDV was measured in the LM.</p> <p>Results</p> <p>interpretable Doppler signal could be obtained in 24 patients (88% feasibility); therefore these patients entered the final analysis. MLA was 7.1 ± 2.7 mm². TTDE measured PDV correlated significantly with IVUS-derived MLA (r = -0.46, p < 0.05) and plaque burden (r = 0.51, p < 0.05). Using a velocity cut-off of 112 cm/sec TTDE showed a 92% sensitivity and 62% specificity to identify IVUS-significant (MLA < 6 mm²) LM stenosis.</p> <p>Conclusion</p> <p>In angiographically borderline LM disease, resting PDV from transthoracic echocardiography is increased in presence of increased plaque burden by IVUS. TTDE evaluation might be a useful adjunct to other invasive and non-invasive methods in the assessment of borderline LM lesions. Further, large scale studies are needed to establish the exact cut-off value of PDV for routine clinical application.</p

Minor psychiatric disorders among Brazilian ragpickers: a cross-sectional study

BACKGROUND: Ragpickers are informal workers who collect recyclable materials to earn a small wage. Their life and working conditions are extremely difficult. We examined minor psychiatric disorders (MPD) among a cohort of ragpickers in Pelotas, a city in southern Brazil. METHODS: Ragpickers were matched by sex, age, and years of schooling with a sample of non-ragpickers from the same poor neighborhoods. The cross-sectional study gathered data by interview on 990 individuals in 2004. MPD were assessed using a standard self-reporting questionnaire, the SRQ-20. RESULTS: The prevalence of MPD among ragpickers was 44.7%, higher than reported by neighborhood controls (33.6%; p < 0.001). MPD were more common among females, those of lower economic level, smokers and alcoholics. Among occupational characteristics, MPD prevalence was associated with frequent static postures, low job satisfaction and recent work accidents. CONCLUSION: Ragpickers more frequently report MPD than other poor workers living in the same neighborhoods, with many of the same life conditions. Improving the work lives of these precarious workers should address not only the physical hazards of their jobs but their mental and emotional health as well

Les enseignant.e.s suisses romand.e.s face au genre : l'agir enseignant entre politiques éducatives et expériences vécues

International audienceCette contribution s’attache à comprendre ce qui est à la source des représentations et despratiques des enseignant.e.s de l’école obligatoire en ce qui concerne l’éducation à l’égalitéentre les sexes en Suisse romande. Elle interroge les facteurs qui incitent les enseignant.e.s àsensibiliser leurs élèves à cette question ou, au contraire, à l’ignorer. La dimension pluriellede l’institution scolaire, qui offre des référents divers à ses employé.e.s, inscrit l’agirenseignant dans un vaste espace d’appropriation des politiques publiques par les acteurs, etfait écho tant aux « savoirs savants » qu’aux « savoirs d’expérience » qui ont marqué leurstrajectoires de formation, de profession et de vie. Après avoir rapidement examiné lespolitiques éducatives en la matière et en vigueur dans l’espace suisse romand, cet article rendcompte des pratiques déclarées par les enseignant.e.s dans le questionnaire qui leur a étéadressé. Il précise ensuite, grâce aux entretiens réalisés avec certain.e.s d’entre elles et eux,quels facteurs favorisent des pratiques scolaires en faveur de l’égalité des sexes mais aussi enquels termes ces pratiques divergent selon les conceptions que les enseignant.e.s se font duproblème
