Long run relationship between economic growth, export, population and investment of Ethiopia

The objective of this study is to examine the long-run relationship between economic growth, population, export, and investment in Ethiopia using annual data collected from the World development indicator, and FAOSTAT for 18 years from 1990-2007 E.C. Co integration and Granger Causality test. Stationary properties of the data and the order of integration of the data were tested using the Augmented Dickey-Fuller (ADF) test. Variables were non-stationary at levels but stationary in first differences. The long-run effects of Population, export and investment on Economic growth indicated that these variables are positively related to economic growth and statistically significant at 1% level. Int.

Comparison of stroke knowledge before and after education in Ethiopia (The ask project)

Background: In order to address the growing burden of stroke in Africa, it is essential to have teaching tools that are accessible to a wide variety of communities. Resources for stroke, recognition of symptoms, steps to assist a stroke victim, or any educational tools are scarce. In order to increase education about stroke, we introduced a stroke education intervention in Bahir Dar, Ethiopia in the Amharic language. The aim of the intervention was to see if stroke knowledge and recognition of stroke symptoms increased post-education. Methods: An anonymous pre-test questionnaire was given to identify their baseline stroke knowledge, and then participants viewed the video about stroke. The Amharic BE-FAST acronym was introduced in the video to evaluate participants’ retention of stroke symptoms, while emphasizing the importance of rapid response. Participants were given a survey to post-test survey of their short-term memory recall, along with another satisfaction survey. Results: Over 50% of participants remembered all five letters of the Amharic BE-FAST acronym, nearly 80% answered that they learned about stroke prevention, 90% were satisfied with the video, and 98% thought it should be available widely to the general public. The data presented showed that there was an improvement in stroke education retention with the use of the stroke education video. Conclusions: The Amharic BE-FAST acronym demonstrated to be an effective tool in communicating the symptoms of stroke from English to Amharic. Stroke education was well received, which provided insight on how to design and implement new medical concepts in native languages.   French title:Connaissances sur les accidents vasulaires cerebraux avant et apres une education en Éthiopie (Projet ask)   Introduction: Afin de faire face au fardeau croissant des AVC en Afrique, il est essentiel de disposer d'outils pédagogiques accssibles à une grande variété de communautés. Les ressources pour l'AVC, la reconnaissance des symptômes, les étapes pour aider une victime d'AVC ou tout autre outil éducatif sont rares. Afin d'accroître l'éducation sur l'AVC, nous avons introduit une intervention d'éducation sur l'AVC à Bahir Dar, en Ethiopie, en langue amharique. Le but de l'intervention était de voir si la connaissance et la reconnaissance des symptômes de l'AVC augmentaient après l'éducation. Méthodes: Un questionnaire pré-test anonyme a été donné pour identifier leurs connaissances de base sur l'AVC, puis les participants ont visionné la vidéo sur l'AVC. L'acronyme amharique BE-FAST a été introduit dans la vidéo pour évaluer la rétention des symptômes d'AVC par les participants, tout en soulignant l'importance d'une réponse rapide. Les participants ont reçu une enquête pour post-test de leur mémoire à court terme, ainsi qu'une autre enquête de satisfaction. Résultats: Plus de 50% des participants se sont souvenus des cinq lettres de l'acronyme amharique BE-FAST, près de 80% ont répondu avoir appris la prévention des AVC, 90% étaient satisfaits de la vidéo et 98% pensaient qu'elle devrait être largement accessible au grand public. Les données présentées ont montré qu'il y avait une amélioration de la rétention de l'éducation sur l'AVC grâce à l'utilisation de la vidéo d'éducation sur l'AVC. Conclusion: L'acronyme amharique BE-FAST s'est révélé être un outil efficace pour communiquer les symptômes de l'AVC de l'anglais à l'amharique. L'éducation sur l'AVC a été bien accueillie, ce qui a permis de comprendre comment concevoir et mettre en oeuvre de nouveaux concepts médicaux dans les langues maternelles

Perioperative capacity and contextual challenges in teaching hospitals of southern Ethiopia: explanatory sequential mixed-methods research

Abstract Background Previous Ethiopian literature on surgical capacity and challenges has focused on quantitative investigations, lacking contextual understanding. This explanatory sequential mixed-methods research (MMR) aimed to assess perioperative capacity and contextual challenges at three teaching hospitals in southern Ethiopia. Methods A quantitative survey assessed workforce, infrastructure, service delivery, financing, and information systems. The survey findings were explained by qualitative semi-structured interviews of twenty perioperative providers. Descriptive statistics were integrated with qualitative thematic analysis findings using the narrative waving approach. Key findings from both datasets were linked using a joint display table. Results The survey revealed shortages in the specialist workforce (with a ratio of 0.58 per 100,000 population), surgical volume (at 115 surgeries per 100,000 population), equipment, supplies, financing, and perioperative data tracking. Hospitals’ radiology services and blood products were only available 25–50% of the time, while anesthetic agents and essential laboratory services were often available 51–75% of the time. Perioperative management protocols were used rarely (1–25% of the time). Over 90% of patients lack health insurance coverage. Qualitative data also revealed scarcity of perioperative resources and equipment; unaffordable perioperative costs, lack of health insurance coverage, and unforeseen expenses; poor patient safety culture and communication barriers across the perioperative continuum of care; workforce shortages, job dissatisfaction, and concerns of competence; and weak national governance, and sociopolitical turmoil, and global market volatility exacerbating local challenges. These challenges are linked to risks in quality of care and patient safety, according to clinicians. Conclusion The study identifies deficiencies in the health system and sociopolitical landscape affecting safe surgery conduct. It highlights the need for comprehensive health system strengthening to expand workforce, upgrade facilities, improve safety culture, resilience, and leadership to ensure timely access to essential surgery. Exploring external factors, such as the impact of national governance and sociopolitical stability on reform efforts is also essential

Phase-locking of magnetic islands diagnosed by ECE-imaging

Millimeter-wave imaging diagnostics identify phase-locking and the satisfaction of 3-wave coupling selection criteria among multiple magnetic island chains by providing a localized, internal measurement of the 2D power spectral density, S(ω, k pol ). In high-confinement tokamak discharges, these interactions impact both plasma rotation and tearing stability. Nonlinear coupling among neoclassical tearing modes of different n-number, with islands not satisfying the poloidal mode number selection criterion ⟨m, m ′, m − m ′⟩, contributes to a reduction in core rotation and flow shear in the vicinity of the modes

Extent and severity of coronary artery disease by coronary CT angiography is associated with elevated left ventricular diastolic pressures and worsening diastolic function

BACKGROUND: Patients with flow-limiting coronary stenoses exhibit elevated left ventricular end-diastolic pressure (LVEDP) and abnormal left ventricular (LV) relaxation. OBJECTIVE: We investigated the relationship of extent and severity of coronary artery disease (CAD) by coronary CT angiography (CTA) to LVEDP and measures of LV diastolic dysfunction. METHODS: We identified consecutive patients undergoing coronary CTA and transthoracic echocardiography who were assessed for diastolic function. CAD was evaluated on a per-patient, per-vessel, and per-segment basis for intraluminal diameter stenosis by using an 18-segment model (0 = none, 1 = 1%-49%, 2 = 50%-69%, and 3 = 70%-100%) and summed over segments to obtain overall coronary plaque burden (segment stenosis score [SSS]; maximum = 54). Transthoracic echocardiography evaluated mitral inflow E wave-to-A wave ratio, tissue Doppler early mitral annual tissue velocity axial excursion, stage of diastolic dysfunction, and LV dimensions and estimated LVEDP from the ratio of mitral inflow velocity to early mitral annular (medial) tissue velocity. RESULTS: Four hundred seventy-eight patients (57% women; mean age, 57.9 +/- 14.6 years; 24.9% prior CAD) comprised the study population. Increasing per-patient maximal coronary stenosis, number of vessels with obstructive stenosis, and SSS were associated with increased LVEDP. The prevalence of advanced diastolic dysfunction increased with greater number of obstructive vessels. In multivariable analyses, SSS was associated with increased LVEDP (0.8 mm Hg per tertile increase in SSS, 0.5-1.1; P \u3c .001); reduced E\u27 axial excursion (-0.3; 95% confidence interval [CI], -0.5 to -0.1; P = .001), increased LV mass index (1.6 g/m(2) per tertile increase in SSS; P = .04), and increased relative wall thickness (0.005; 95% CI, 0.004-0.009; P = .03), with consistent relationships persisting even among persons with per-patient maximal stenosis \u3c 50% and LV ejection fraction \u3e\u3e= 55%. CONCLUSIONS: Extent and severity of obstructive as well as nonobstructive CAD by coronary CTA are associated with increased LVEDP and measures of diastolic dysfunction. Elsevier Inc.

Surgery and outcome of infective endocarditis in octogenarians: prospective data from the ESC EORP EURO-ENDO registry

Purpose: High mortality and a limited performance of valvular surgery are typical features of infective endocarditis (IE) in octogenarians, even though surgical treatment is a major determinant of a successful outcome in IE. Methods: Data from the prospective multicentre ESC EORP EURO-ENDO registry were used to assess the prognostic role of valvular surgery depending on age. Results: As compared to < 80 yo patients, ≥ 80 yo had lower rates of theoretical indication for valvular surgery (49.1% vs. 60.3%, p < 0.001), of surgery performed (37.0% vs. 75.5%, p < 0.001), and a higher in-hospital (25.9% vs. 15.8%, p < 0.001) and 1-year mortality (41.3% vs. 22.2%, p < 0.001). By multivariable analysis, age per se was not predictive of 1-year mortality, but lack of surgical procedures when indicated was strongly predictive (HR 2.98 [2.43–3.66]). By propensity analysis, 304 ≥ 80 yo were matched to 608 < 80 yo patients. Propensity analysis confirmed the lower rate of indication for valvular surgery (51.3% vs. 57.2%, p = 0.031) and of surgery performed (35.3% vs. 68.4%, p < 0.0001) in ≥ 80 yo. Overall mortality remained higher in ≥ 80 yo (in-hospital: HR 1.50[1.06–2.13], p = 0.0210; 1-yr: HR 1.58[1.21–2.05], p = 0.0006), but was not different from that of < 80 yo among those who had surgery (in-hospital: 19.7% vs. 20.0%, p = 0.4236; 1-year: 27.3% vs. 25.5%, p = 0.7176). Conclusion: Although mortality rates are consistently higher in ≥ 80 yo patients than in < 80 yo patients in the general population, mortality of surgery in ≥ 80 yo is similar to < 80 yo after matching patients. These results confirm the importance of a better recognition of surgical indication and of an increased performance of surgery in ≥ 80 yo patients

Socio-Economic Variations Determine the Clinical Presentation, Aetiology and Outcome of Infective Endocarditis: a Prospective Cohort Study from the ESC-EORP EURO-ENDO (European Infective Endocarditis) Registry

Background: Infective endocarditis (IE) is a life-threatening disease associated with high mortality and morbidity worldwide. We sought to determine how socio-economic factors might influence its epidemiology, clinical presentation, investigation and management, and outcome, in a large international multi-centre registry. Methods: The EurObservationalProgramme (EORP) of the European Society of Cardiology (ESC) EURO-ENDO registry comprises a prospective cohort of 3113 adult patients admitted for IE in 156 hospitals in 40 countries between January 2016 and March 2018. Patients were separated in 3 groups, according to World Bank economic stratification (Group 1 - high income [75.6%]; Group 2 - upper-middle income [15.4%]; Group 3 - lower-middle income [9.1%]). Results: Group 3 patients were younger (median age [IQR]: Group 1 - 66 [53-75] years; Group 2 - 57 [41-68] years; Group 3 - 33 [26-43] years; p<0.001) with a higher frequency of smokers, intravenous drug use and human immunodeficiency virus (HIV) infection (all p<0.001) and presented later (median [IQR) days since symptom onset: Group 1 - 12 [3-35]; Group 2 - 19 [6-54]; Group 3 - 31 [12-62]; p<0.001) with a higher likelihood of developing congestive heart failure (13.6%; 11.1%; and 22.6%, respectively; p<0.001) and persistent fever (9.8%; 14.2%; 27.9%; p<0.001). Among 2157 (69.3%) patients with theoretical indication for cardiac surgery, surgery was performed less frequently in Group 3 patients (75.5%, 76.8% and 51.3%, respectively p<0.001) who also demonstrated the highest mortality (15.0%, 23.0% and 23.7%, respectively; p<0.001). Conclusions: Socio-economic factors influence the clinical profile of patients presenting with IE across the world. Despite younger age, patients from the poorest countries presented with more frequent complications and higher mortality associated with delayed diagnosis and lower use of surgery
