GHTM Sessions 2022 CCID03 » Back to the future: Fluorescent Acid-fast-Stains for TB-diagnosis and beyond

  • From: 09/02/2022
  • To: 09/02/2022
  • Location: ZOOM | 11h00

Traditional light-microscopy of stained smears may be replaced by fluorescent stains.
The auramine-O Acid-Fast-Stain (AFS) does not stain the cell-wall (mycolic acids), but is a classical DNA/RNA stain, whereby the cell wall only protects the microorganisms from decolorization by the acid. Confirmation of this new concept opens up the possibility to use this stain in different contexts: a) Auramine-O AFS allows the simple detection of Schistosome eggs; b) Auramine-O AFS allows detection of mycobacteria in histological samples; c) newer nucleic acid-stains may increase (broaden) the application of this stain.

GHTM Sessions 2022 VBD01 » Optimising strategies for control and elimination of neglected tropical diseases (NTDs)

  • From: 14/01/2022
  • To: 14/01/2022
  • Location: ZOOM | 11h00

NTDs cause serious morbidity and disability, affecting 2 billion people in low- and middle-income countries. The main strategy for control of key NTDs is preventive chemotherapy (PC), the regular delivery of drugs to entire communities or specific sub-groups, such as children. PC NTDs of global importance include soil-transmitted helminths, schistosomiasis, scabies, trachoma and yaws. The Kirby’s NTD research group is leading large-scale intervention research linked to novel diagnostics, social science, health economics and mathematical modelling aiming to contribute to the control and elimination of PC NTDs in the Asia-Pacific region and Africa. The RG leader will present an overview of that research with examples including cluster randomised control trials in Vietnam, Solomon Islands and Fiji; and impact assessments of PC programs in Vanuatu, Solomon Islands, Nauru, East Timor and Angola.

GHTM Sessions 2021 CCID09 » Point-of-care ultrasound in Schistosoma haematobium infections – a new approach to detect potentially carcinogenic lesions

  • From: 21/07/2021
  • To: 21/07/2021
  • Location: ZOOM | 11h00

Recently, emerged a tool that can be useful to identify and evaluate potentially carcinogenic bladder or kidney damages: point-of-care ultrasound.
The research on urinary tract lesions as infection symptoms, with the development of ultrasound evaluation protocols, might enable early treatment and prevent cancer progression among millions of people.
