    Job satisfaction is an important determinant of health worker motivation, retention, and performance, all of which are critical to improving the functioning of health systems in low- and middle-income countries. A number of small-scale surveys have measured the job satisfaction and intention to leave of individual health worker cadres in different settings, but there are few multi-country and multi-cadre comparative studies. The objective of this study was to compare the job satisfaction and intention to leave of different categories of health workers in Tanzania, Malawi, and South Africa. We undertook a cross-sectional survey of a stratified cluster sample of 2,220 health workers, 564 from Tanzania, 939 from Malawi, and 717 from South Africa. Participants completed a self-administered questionnaire, which included demographic information, a 10-item job satisfaction scale, and one question on intention to leave. Multiple regression was used to identify significant predictors of job satisfaction and intention to leave. There were statistically significant differences in job satisfaction and intention to leave between the three countries. Approximately 52.1% of health workers in South Africa were satisfied with their jobs compared to 71% from Malawi and 82.6% from Tanzania (χ2=140.3, p<0.001). 18.8% of health workers in Tanzania and 26.5% in Malawi indicated that they were actively seeking employment elsewhere, compared to 41.4% in South Africa (χ2=83.5, p<0.001). The country differences were confirmed by multiple regression. The study also confirmed that job satisfaction is statistically related to intention to leave. We have shown differences in the levels of job satisfaction and intention to leave between different groups of health workers from Tanzania, Malawi, and South Africa. Our results caution against generalising about the effectiveness of interventions in different contexts and highlight the need for less standardised and more targeted HRH strategies than has been practised to date

    Gostaria de falar algumas palavras sobre um tipo de contrato que está entrando muito em moda entre nós - o de leasing para o qual existe um termo bem nosso chamado arrendamento mercantil. O arrendamento mercantil ou leasing está assumindo entre nós certa importância e tende a se tornar cada vez mais importante. A bibliografia brasileira sobre a matéria, mais recente, é muito precária e há alguns poucos trabalhos, mas realmente nós estamos carecendo de um trabalho mais profundo sobre o assunto que vem revestido de novas características.Número padronizado: v. 40, n. 3 (1983)Revista do Serviço Público, ano 40 v.111, n. 3, p. 76-78DesenvolvimentoISSN eletrônico: 2357-8017ISSN impresso: 0034-924

    AbstractIntroductionThe prevalence of ADHD among patients with substance use disorder (SUD) is substantial. This study addressed the following research questions: Are early developmental, temperamental and educational problems overrepresented among SUD patients with ADHD compared to SUD patients without ADHD? Do this comorbid group receive early help for their ADHD, and are there signs of self-medicating with illicit central stimulants?MethodAn international, multi-centre cross-sectional study was carried out involving seven European countries, with 1205 patients in treatment for SUD. The mean age was 40years and 27% of the sample was female. All participants were interviewed with the Mini International Neuropsychiatric Interview Plus and the Conners' Adult ADHD Diagnostic Interview for DSM-IV.ResultsSUD patients with ADHD (n=196; 16.3% of the total sample) had a significantly slower infant development than SUD patients without ADHD (n=1,009; 83.4%), had greater problems controlling their temperament, and had lower educational attainment. Only 24 (12%) of the current ADHD positive patients had been diagnosed and treated during childhood and/or adolescence. Finally, SUD patients with ADHD were more likely to have central stimulants or cannabis as their primary substance of abuse, whereas alcohol use was more likely to be the primary substance of abuse in SUD patients without ADHD.ConclusionThe results emphasize the importance of early identification of ADHD and targeted interventions in the health and school system, as well as in the addiction field

    Cis-regulation of microRNA expression by scaffold/matrix-attachment regions

    microRNAs (miRNAs) spatio-temporally modulate gene expression; however, very little is known about the regulation of their expression. Here, we hypothesized that the well-known cis-regulatory elements of gene expression, scaffold/matrix-attachment regions (MARs) could modulate miRNA expression. Accordingly, we found MARs to be enriched in the upstream regions of miRNA genes. To determine their role in cell type-specific expression of miRNAs, we examined four individual miRNAs (let-7b, miR-17, miR-93 and miR-221) and the miR-17–92 cluster, known to be overexpressed in neuroblastoma. Our results show that MARs indeed define the cell-specific expression of these miRNAs by tethering the chromatin to nuclear matrix. This is brought about by cell type-specific binding of HMG I/Y protein to MARs that then promotes the local acetylation of histones, serving as boundary elements for gene activation. The binding, chromatin tethering and gene activation by HMG I/Y was not observed in fibroblast control cells but were restricted to neuroblastoma cells. This study implies that the association of MAR binding proteins to MARs could dictate the tissue/context specific regulation of miRNA genes by serving as a boundary element signaling the transcriptional activation

    Reworlding: participatory design capabilities to tackle socio-environmental challenges

    Get PDF
    Rising societal polarisations around health and climate crises have brought more attention to the close relations between social and environmental challenges. These polarisations triggered an interest in the participatory design (PD) field in developing approaches that enhance connections between diverse actors operating across societal and environmental sectors. However, the capabilities needed for these approaches have not been sufficiently articulated in PD research and education. To fill in this gap, we define 'reworlding' as an operation of self-critique within PD that engages with capabilities needed to reveal and articulate radical interdependencies between humans and more-than-humans, across social and environmental worlds, and within situated contexts. We propose both the redefinition of the design capabilities needed for (re)connecting these worlds (retracing, reconnecting, reimagining and reinstitutioning), as well as a reconsideration of learning environments where these capabilities can be tested and enhanced

    BACKGROUND: A number of case-control studies were conducted to investigate the association of SULT1A1 R213H polymorphisms with colorectal cancer (CRC) in humans. But the results were not always consistent. We performed a meta-analysis to examine the association between the SULT1A1 R213H polymorphism and CRC. METHODS AND FINDINGS: Data were collected from the following electronic databases: PubMed, Elsevier Science Direct, Excerpta Medica Database, and Chinese Biomedical Literature Database, with the last report up to September 2010. A total of 12 studies including 3,549 cases and 5,610 controls based on the search criteria were involved in this meta-analysis. Overall, no significant association of this polymorphism with CRC was found (H versus R: OR = 1.04, 95%CI = 0.94-1.16, P = 0.46; HR+HH versus RR: OR = 1.01, 95%CI = 0.92-1.11, P = 0.81; HH versus RR+HR: OR = 1.01, 95%CI = 0.74-1.38, P = 0.95; HH versus RR: OR = 1.00, 95%CI = 0.77-1.31, P = 0.98; HR versus RR: OR = 1.01, 95%CI = 0.92-1.11, P = 0.86). In subgroup analysis, we also did not find any significant association in Cauasians (H versus R: OR = 1.02, 95%CI = 0.92-1.15, P = 0.68; HR+HH versus RR: OR = 0.99, 95%CI = 0.91-1.09, P = 0.90; HH versus RR+HR: OR = 1.01, 95%CI = 0.73-1.39, P = 0.97; HH versus RR: OR = 0.99, 95%CI = 0.75-1.31, P = 0.94; HR versus RR: OR = 0.99, 95%CI = 0.90-1.09, P = 0.85). The results were not materially altered after the studies which did not fulfill Hardy-Weinberg equilibrium were excluded (H versus R: OR = 1.06, 95%CI = 0.95-1.19, P = 0.31; HR+HH versus RR: OR = 1.03, 95%CI = 0.93-1.13, P = 0.56; HH versus RR+HR: OR = 1.10, 95%CI = 0.78-1.56, P = 0.57; HH versus RR: OR = 1.09, 95%CI = 0.83-1.44, P = 0.53; HR versus RR: OR = 1.02, 95%CI = 0.92-1.13, P = 0.75). CONCLUSION: This meta-analysis demonstrates that there is no association between the SULT1A1 R213H polymorphism and CRC

    Starches, Sugars and Obesity

    The rising prevalence of obesity, not only in adults but also in children and adolescents, is one of the most important public health problems in developed and developing countries. As one possible way to tackle obesity, a great interest has been stimulated in understanding the relationship between different types of dietary carbohydrate and appetite regulation, body weight and body composition. The present article reviews the conclusions from recent reviews and meta-analyses on the effects of different starches and sugars on body weight management and metabolic disturbances, and provides an update of the most recent studies on this topic. From the literature reviewed in this paper, potential beneficial effects of intake of starchy foods, especially those containing slowly-digestible and resistant starches, and potential detrimental effects of high intakes of fructose become apparent. This supports the intake of whole grains, legumes and vegetables, which contain more appropriate sources of carbohydrates associated with reduced risk of cardiovascular and other chronic diseases, rather than foods rich in sugars, especially in the form of sugar-sweetened beverages
