National Survey of Noncommunicable Diseases in Seychelles, 2013-2014 (Seychelles Heart Study IV) : methods and main findings
This report provides information on selected summary results of the National Survey of Noncommunicable Diseases in Seychelles in 2013â2014 (Seychelles Heart Study IV). The survey is also referred shortly as the "2013 Survey" in this report. Overall crude results were reported in a comprehensive report in November 2014. Further detailed analyses and recommendations on particular topics will be performed separately
Traitement du signal par modulation d'ouverture dans les antennes : Reseaux
La modulation d'ouverture est un procĂ©dĂ© de traitement des signaux d'antennes consistant Ă faire varier au cours du temps les dimensions de l'ouverture rayonnante et qui prĂ©sente de l'intĂ©rĂȘt surtout pour les antennes-rĂ©seaux Ă grand nombre d'Ă©lĂ©ments pour micro-ondes. Nous nous proposons de montrer comment on peut rĂ©aliser, Ă l'aide de commutateurs rapides (par exemple, Ă diodes P.I.N.) des antennes Ă ouverture modulĂ©e possĂ©dant deux voies de sortie : l'une optimisĂ©e en ce qui concerne l'ambiguĂŻtĂ© angulaire, l'autre optimisĂ©e en pouvoir sĂ©parateur. D'autres applications s'ont possibles, comme la synthĂšse de diagrammes Ă©volutifs
Situation et enjeux sanitaires aux Seychelles en 2012 [Health situation and issues in the Seychelles in 2012]
Off the coast of Kenya, the Seychelles, home to 87,400 inhabitants mostly of African origin, have largely completed their demographic and epidemiologic transitions. Major investments in infrastructure and social services have fostered steady economic growth. Health care and education are free. The predominance of chronic non-communicable diseases and rapid aging of the population nonetheless present significant challenges for public health and the health system. Like the other small island states in the region, the Seychelles continue to be threatened by arbovirus outbreaks. Health indicators are good, but the geographic isolation, the small and aging population, and limited resources make a major challenge maintaining and sustaining an effective workforce of health professionals, a constantly evolving technical platform, and increasing amount of medications particularly in view of the increasing burden of chronic diseases
Burden, risk factors, neurosurgical evacuation outcomes, and predictors of mortality among traumatic brain injury patients with expansive intracranial hematomas in Uganda: a mixed methods study design
Abstract
Background
Expansive intracranial hematomas (EIH) following traumatic brain injury (TBI) continue to be a public health problem in Uganda. Data is limited regarding the neurosurgical outcomes of TBI patients. This study investigated the neurosurgical outcomes and associated risk factors of EIH among TBI patients at Mulago National Referral Hospital (MNRH).
Methods
A total of 324 subjects were enrolled using a prospective cohort study. Socio-demographic, risk factors and complications were collected using a study questionnaire. Study participants were followed up for 180Â days. Univariate, multivariable, Cox regression analyses, Kaplan Meir survival curves, and log rank tests were sequentially conducted. P-values ofâ<â0.05 at 95% Confidence interval (CI) were considered to be statistically significant.
Results
Of the 324 patients with intracranial hematomas, 80.6% were male. The mean age of the study participants was 37.5â±â17.4 years. Prevalence of EIH was 59.3% (0.59 (95% CI: 0.54 to 0.65)). Participants who were aged 39 years and above; PRâ=â1.54 (95% CI: 1.20 to 1.97; Pâ=â0.001), and those who smoke PRâ=â1.21 (95% CI: 1.00 to 1.47; Pâ=â0.048), and presence of swirl sign PRâ=â2.26 (95% CI: 1.29 to 3.95; Pâ=â0.004) were found to be at higher risk for EIH. Kaplan Meier survival curve indicated that mortality at the 16-month follow-up was 53.4% (95% CI: 28.1 to 85.0). Multivariate Cox regression indicated that the predictors of mortality were old age, MAP above 95 mmHg, low GCS, complications such as infection, spasticity, wound dehiscence, CSF leaks, having GOSâ<â3, QoLIBRIâ<â50, SDH, contusion, and EIH.
Conclusion
EIH is common in Uganda following RTA with an occurrence of 59.3% and a 16-month higher mortality rate. An increased age above 39Â years, smoking, having severe systemic disease, and the presence of swirl sign are independent risk factors. Old age, MAP above 95Â mmHg, low GCS, complications such as infection, spasticity, wound dehiscence, CSF leaks, having a GOSâ<â3, QoLIBRIâ<â50, ASDH, and contusion are predictors of mortality. These findings imply that all patients with intracranial hematomas (IH) need to be monitored closely and a repeat CT scan to be done within a specific period following their initial CT scan. We recommend the development of a protocol for specific surgical and medical interventions that can be implemented for patients at moderate and severe risk for EIH.
