Diagnostic Radiology in Liberia: A Country Report

Liberia is a tropical country located south of the Sahara Desert in coastal West Africa. It lies at 6 °30’ North Latitude and 9° 30’ West Longitude and is bordered by Guinea, Cote d’Ivoire, Sierra Leone and the Atlantic Ocean. Liberia has three distinct topographical areas: 1) coastal plain, creeks, lagoons and mangrove swamps; 2) rolling, forested hills with elevations up to 500 feet that cover most of the country; and 3) low mountains and plateaus in the Northern highlands with elevations reaching 4,748 feet (Nimba Mountains). Liberia is home to approximately four million people and is roughly the size of the US state of Tennessee. Named after former US President James Monroe, Liberia’s capital Monrovia is a coastal city with a population of one million (1). There are two major seasons in Liberia: dry and rainy. The dry season occurs between December and March, and is is characterized by warm days and cool nights, with risk of sand storms from the Sahara Desert (2). The rainy season occurs between mid-April and mid-November. The average annual rainfall is 200 inches on the coast and decreases to 80 inches in areas farthest inland, and the average temperature is 27 degrees Celsius (81 degrees Fahrenheit) (1). Liberia is a low-income country that relies heavily on foreign aid (3). Liberia is the seventh poorest nation in the world, ranking 31st among 46 sub-Sarahan African countries in national income. In 2013, Liberia’s per capita GDP was $900 US (3). Liberia’s economy depends heavily on natural resources, with mining and agriculture being the dominant industries. Iron exportation has grown and in 2013 overcame rubber as Liberia’s top export. According to the 2013 Central Bank of Liberia (CBL) Annual Report, iron ore and rubber represent 82% of Liberia’s total exports (4). Civil war destroyed much of Liberia’s economy, including critical infrastructure in and around Monrovia. Although conditions are favorable for agriculture, Liberia does not produce nearly enough food to meet the demands of its population. The country imports large quantities of food, with rice alone accounting for 10% of its overall imports (5)

Gestational Age Estimation Based on Fetal Pelvimetry on Fetal Ultrasound in Iraqi Women

Ultrasound is an integral part of obstetric practice, and assessment of gestational age (GA) is a central element of obstetric ultrasonography. Sonographic estimation of GA is derived from calculations based on fetal measurements. Numerous equations for GA calculation from fetal biometry have been adopted in routine practice. This study reports a new method of estimating GA in the second and third trimester using interischial distance (IID), the distance between the two ischial primary ossification centers, on fetal ultrasound. Four hundred women with uncomplicated normal singleton pregnancies from 16 weeks to term were examined. Standard fetal obstetric ultrasound was done measuring biparietal diameter (BPD) and femur length (FL) for each fetus. The IID, in millimeters, was correlated with the GA in weeks based upon the BPD and FL individually, and the BPD and FL together. Statistical analysis showed strong correlation between the IID and GA calculated from the FL with correlation coefficient (r =0.989, P \u3c 0.001). Strong linear correlation was also found between the IID and GA based upon BPD and BPD+FL. Further statistical analysis using regression equations also showed that the IID was slightly wider in female fetuses, but this difference was not statistically significant. Resulting from this analysis, we have arrived at an easy-to-use equation: GA Weeks = (IID mm + 8) ±1 week. We feel this method can be especially applicable in the developing world, where midwives may not have access to software for fetal biometry in their basic handheld ultrasound machines. Even more sophisticated machines may not come with loaded software for obstetrics analysis. There are several limitations to this study, discussed below. We recommend further studies correlating the IID with other biometric parameters

CBRS Spectrum Sharing between LTE-U and WiFi: A Multiarmed Bandit Approach

The surge of mobile devices such as smartphone and tablets requires additional capacity. To achieve ubiquitous and high data rate Internet connectivity, effective spectrum sharing and utilization of the wireless spectrum carry critical importance. In this paper, we consider the use of unlicensed LTE (LTE-U) technology in the 3.5 GHz Citizens Broadband Radio Service (CBRS) band and develop a multiarmed bandit (MAB) based spectrum sharing technique for a smooth coexistence with WiFi. In particular, we consider LTE-U to operate as a General Authorized Access (GAA) user; hereby MAB is used to adaptively optimize the transmission duty cycle of LTE-U transmissions. Additionally, we incorporate downlink power control which yields a high energy efficiency and interference suppression. Simulation results demonstrate a significant improvement in the aggregate capacity (approximately 33%) and cell-edge throughput of coexisting LTE-U and WiFi networks for different base station densities and user densities

Feasibility of Silicon Quantum Dots as a Biomarker for the Bioimaging of Tear Film

This study investigated the fluorescence and biocompatibility of hydrophilic silicon quantum dots (SiQDs) that are doped with scandium (Sc-SiQDs), copper (Cu-SiQDs), and zinc (Zn-SiQDs), indicating their feasibility for the bioimaging of tear film. SiQDs were investigated for fluorescence emission by the in vitro imaging of artificial tears (TheraTears®), using an optical imaging system. A trypan blue exclusion test and MTT assay were used to evaluate the cytotoxicity of SiQDs to cultured human corneal epithelial cells. No difference was observed between the fluorescence emission of Sc-SiQDs and Cu-SiQDs at any concentration. On average, SiQDs showed stable fluorescence, while Sc-SiQDs and Cu-SiQDs showed brighter fluorescence emissions than Zn-SiQDs. Cu-SiQDs and Sc-SiQDs showed a broader safe concentration range than Zn-SiQDs. Cu-SiQDs and Zn-SiQDs tend to aggregate more substantially in TheraTears® than Sc-SiQDs. This study elucidates the feasibility of hydrophilic Sc-SiQDs in studying the tear film’s aqueous layer

EVALUATION OF PHYTOCHEMICAL COMPOUNDS IN Moringa oliefera Lam. EXTRACTS ON CYTOTOXICITY OF MCF-7 CELL LINE

Moringa olifera Lam. which called "Miracle tree" was an enormous usage of medical, nutritional and economic benefits so its leaves and roots extracts were vitro examined for phytochemicals contents, antioxidant, and cytotoxicity against MCF-7 cell line. Leaves and roots both extracts were estimate using 2,2-di phenyl-1-picryl hydrazyl (DPPH) radical scavenging assay and high performance liquid chromatography (HPLC) to determine phenolic and flavonoids compounds. The leaves  aqueous and ethyl acetate extracts  contained a significantly (p<0.05) more phenolic compounds than root extracts, while roots ethyl acetate extracts were significantly more active  in DPPH assay comparing with aqueous extracts . However, the leaves aqueous extract and roots ethyl extracts were contained high values flavonoids compound but in case of phenolic compounds the aqueous roots ex tract recorded the greatest highest number followed by the leaves ethyl acetate extract. The ethyl acetate extractions for leaves and roots have a high inhibition percentage against breast adenocarcinoma MCF-7 cell line comparing with aqueous extracts

Telemonitoring for Patients With Chronic Heart Failure: A Systematic Review

Background Telemonitoring, the use of communication technology to remotely monitor health status, is an appealing strategy for improving disease management. Methods and Results We searched Medline databases, bibliographies, and spoke with experts to review the evidence on telemonitoring in heart failure patients. Interventions included: telephone-based symptom monitoring (n = 5), automated monitoring of signs and symptoms (n = 1), and automated physiologic monitoring (n = 1). Two studies directly compared effectiveness of 2 or more forms of telemonitoring. Study quality and intervention type varied considerably. Six studies suggested reduction in all-cause and heart failure hospitalizations (14% to 55% and 29% to 43%, respectively) or mortality (40% to 56%) with telemonitoring. Of the 3 negative studies, 2 enrolled low-risk patients and patients with access to high quality care, whereas 1 enrolled a very high-risk Hispanic population. Studies comparing forms of telemonitoring demonstrated similar effectiveness. However, intervention costs were higher with more complex programs ($8383 per patient per year) versus less complex programs ($1695 per patient per year). Conclusion The evidence base for telemonitoring in heart failure is currently quite limited. Based on the available data, telemonitoring may be an effective strategy for disease management in high-risk heart failure patients

Extensive production of Neospora caninum tissue cysts in a carnivorous marsupial succumbing to experimental neosporosis

Experimental infections of Sminthopsis crassicaudata, the fat-tailed dunnart, a carnivorous marsupial widely distributed throughout the arid and semi-arid zones of Australia, show that this species can act as an intermediate host for Neospora caninum. In contrast to existing models that develop relatively few N. caninum tissue cysts, dunnarts offer a new animal model in which active neosporosis is dominated by tissue cyst production. The results provide evidence for a sylvatic life cycle of N. caninum in Australia between marsupials and wild dogs. It establishes the foundation for an investigation of the impact and costs of neosporosis to wildlife
