Internet-based biosurveillance methods for vector-borne diseases: Are they novel public health tools or just novelties?
by Simon Pollett, Benjamin M. Althouse, Brett Forshey, George W. Rutherford, Richard G. Jarman Internet-based surveillance methods for vector-borne diseases (VBDs) using “big data” sources such as Google, Twitter, and internet newswire scraping have recently been developed, yet reviews on such “digital disease detection” methods have focused on respiratory pathogens, particularly in high-income regions. Here, we present a narrative review of the literature that has examined the performance of internet-based biosurveillance for diseases caused by vector-borne viruses, parasites, and other pathogens, including Zika, dengue, other arthropod-borne viruses, malaria, leishmaniasis, and Lyme disease across a range of settings, including low- and middle-income countries. The fundamental features, advantages, and drawbacks of each internet big data source are presented for those with varying familiarity of “digital epidemiology.” We conclude with some of the challenges and fu ture directions in using internet-based biosurveillance for the surveillance and control of VBD.
A fully integrated CMOS circuit based on a vector network analyzer and a transmission-line-based detection window for circulating tumor cell (CTC) and exosome analysis is presented for the first time. We have introduced a fully integrated architecture, which eliminates the undesired parasitic components and enables high-sensitivity, to analyze extremely low-concentration CTC in blood. The detection window was designed on the high-sensitive coplanar waveguide line. To validate the operation of the proposed system, a test chip was fabricated using 65-nm CMOS technology. Measurements were performed after adding a tiny lump of...
ConclusionsA diverse range of health education products have been designed and applied for the prevention and control of helminthiases in China. Many products have good features such as specifying the targeted diseases and populations. However, there are significant gaps in terms of both the quantity and quality of products pertaining to some of the diseases. Experiences from the awarded products could be drawn upon to design more products aimed at a range of different helminthiases.
Authors: Atolani O, Oguntoye H, Areh ET, Adeyemi OS, Kambizi L Abstract CONTEXT: Cola gigantea A. Chev. (Sterculiaceae) is an important medicinal tropical flora. OBJECTIVE: The seed oil of C. gigantea, an underutilized tropical plant was investigated for its antioxidant, anti-inflammatory, anti-Toxoplasma, and cytotoxicity activities as well as the chemical composition. MATERIALS AND METHODS: The physicochemical parameters of the seed oil obtained via Soxhlet extraction was determined while the fatty acid and non-fatty acid component were analyzed by gas chromatography-mass spectrometry. The antioxidant act...
[Daily Maverick] While many politicians, world leaders and big corporations speak about the future effects of climate change, poor and impoverished nations are already struggling to battle the consequences of rising global temperatures.
[Gra ça Machel Trust] The Graça Machel Trust, (GMT), the Nelson Mandela Children's Fund, (NMCF) and the Foundation for Community Development (FDC) are greatly concerned about the unfolding effects of Cyclone Idai across parts of Malawi, Mozambique and Zimbabwe. The increasing death toll and numbers of women and children uncounted for is extremely worrisome. The devastation has left communities homeless, unsafe, without food, emergency healthcare and other essential services.
[Namibia Economist] The Southern African Development Community (SADC) in response to the devastation caused by the recent tropical Cyclone Idai has contributed a total of US$500,000 to assist the countries affected.
[VOA] The United Nations says the combined death toll in southern African nations affected by Cyclone Idai has exceeded 700.
(Frontiers) Billions worldwide are infected with tropical worms. Unsurprisingly, most of these people live in poor countries, kept poor by the effects of worm-related malnourishment.What may surprise many is that worms also cause the majority of cases of some cancers in these countries.Published in Frontiers in Medicine as a special article collection on parasite-associated malignancy, new research aims to inform prevention and treatment - and perhaps even turn worms against cancer.
This week's case comes from my lab with photos and video taken by Emily Fernholz. The objects shown were seen in a liver cyst aspirate. Identification?Low power view (4x objective):40x objective:Here's a fun'bird's eye'view (hit the play button twice):
The biting behaviour and dispersal of insect vectors in the field underlies the transmission of many diseases. Here, a novel collection methodology coupled with the molecular analysis of blood-meal sources and...
