Examining Contextual Factors and Individual Value Dimensions of Healthcare Providers Intention to Adopt Electronic Health Technologies in Developing Countries

Part 5: Research in ProgressInternational audienceDespite substantial research on electronic health (e-Health) adoption, there still exist vast differences between resource-rich and resource-poor populations regarding Information Technology adoption. To help bridge the technological gulf between developed and developing countries, this research-in-progress paper examines healthcare providers’ intention to adopt e-health technologies from two perspectives 1) contextual factors (i.e. specific to developing world settings) and 2) individual value dimensions (i.e. cultural, utilitarian, social and personal). The primary output of this paper is a theoretical model merging both the contextual factors and value dimensions; this forms a strong baseline to examine and help ensure the successful adoption of e-Health technologies within developing countries. Future research will be performed to validate the model developed in this paper, with a specific focus on mobile Health in Malawi, Africa

Development and Application of a Standstill Parameter Identification Technique for the Synchronous Generator

This work presents the development of an offline standstill estimation technique, where the synchronous machine is locked at an arbitrary (but known) angle and is excited over a short period of time. The proposed time domain method requires few seconds of captured data in contrast to the well-known standard Standstill Frequency Response (SSFR) technique that could take more than 6 hours to conduct. This is based on nonlinear least squares estimation and algebraic elimination theory. The resulting algorithm is non-iterative where the data is used to construct polynomials that are solved for a finite number of roots which determine the electrical parameter values. Experimental results are presented showing the efficacy of the technique in furnishing the parameters of a salient pole synchronous machine

Growth performance, hepatic gene expression, and plasma biochemistry of rainbow trout fed full-fat meal, defatted meal, oil and chitin from black soldier flies

Insects, such as black soldier flies (BSF), are sustainable alternatives to fishmeal and fish oil that have been shown maintain fish growth performance, especially at low dietary inclusions. However, BSF is commonly processed to remove chitin and oil that may have additional benefits to the immune response and disease resistance of fish. The aim of this study was to investigate the hepatic gene expression and plasma biochemistry of rainbow trout (Oncorhynchus mykiss) fed BSF meals and BSF components. A three-month feeding trial was performed where rainbow trout (90.0 ± 4.0g; mean ± SD) were fed either a control diet or diets that contained: 10 % full-fat BSF, 10 % defatted BSF, 4 % BSF oil, and 1 % BSF chitin. Liver was analyzed for gene expression via qPCR and plasma was analyzed for 21 biochemical markers. The 4 % oil and 1 % chitin diets had the highest effect on growth performance, i.e. final weight (p=0.043) and feed intake (p=0.017), compared to the control diet, while no effects of these diets were found on hepatic gene expression. The 10 % full-fat BSF diet affected gene expression, specifically upregulating the pro-inflammatory cytokine IL-8 (p=0.033), which may be due to the higher content of saturated fatty acids (SFA) and subsequently immune cell activity in the fish or the combination of the SFA and antimicrobial peptides in BSF that stimulate the innate immune system. No other immune and oxidative stress genes, or 21 plasma biochemical markers were found to be significantly affected (p>0.05). This research provides support to include and not remove oil and chitin from BSF since these components can improve growth performance and immune response of rainbow trout

Expressão epidemiológica de outras doenças sexualmente transmissíveis entre portadores de AIDS Epidemiological expression of other sexually transmitted diseases among AIDS patients

Objetivou-se avaliar a freqüência de outras doenças sexualmente transmissíveis (DST) em pacientes portadores de AIDS, identificando-se suas associações epidemiológicas e possíveis relações com as categorias de exposição ao vírus. Os dados foram coletados dos prontuários médicos, identificando-se as DST com base em dados de anamnese, exame físico e exames laboratoriais. Dos portadores de HIV/AIDS, atendidos no hospital estudado, de janeiro de 1986 a janeiro de 1992, 207 constituíram a amostra estudada. Dos pacientes estudados, 88 (42,5%) apresentaram alguma DST e 119 (57,5%) não, resultando proporção de pacientes com DST/pacientes sem DST igual a 0,7. As DST mais prevalentes foram hepatite B (33, 3%), sífilis (30, 3%) e gonorréia (12, 9%). Quanto às categorias de exposição dos indivíduos ao HIV, a mais prevalente foi a sangüínea (44,9%), seguida pela sexual (21,3%), sexual e sangüínea (17, 9%) e indeterminada em 15, 9%. Comparando particularmente as categorias de transmissão sexual e sangüínea do HIV e a presença de outras DST, estas foram significativamente mais freqüentes nos casos cuja categoria de exposição referida foi a sexual.<br>This study was carried out in order to estimate the frequence of other sexually transmitted diseases (STD) among AIDS patients and to identify their epidemiological association and possible relations to the groups most exposed to the virus. The data were collected from the medical case histories and the STD were identified on the basis of data provided by anamnesis, physical examination and laboratory examinations. Of the total of HIV/AIDS patients assisted at the hospital studied (S.Paulo State, Brazil), between January 1986 and January 1992, 207 were included as sample subjects for this survey. Of the patients studied, 88 (42.5%) had some other STD and 119 (57.5%) had no other STD, equivalent to a proportion of 0.7 STD patients-STD to each non-STD patient. The most prevalent STD identified were hepatitis B (33.3%), syphilis (30.3%) and gonorrhoea (12.9%). Concerning the means of transmission by which the patients had probably been infected with HIV, blood transmission was the most prevalent (44.9%); followed by sexual contact (21.3%); sexual/blood (17.9%); in 25.9% it was undetermined. In a particular comparison of sexual and blood transmisson and the presence of other STD a statatiscal difference in those cases that were exposed to sexual transmission was observed
