Ascaris Lumbricoides Diagnosed During Evaluation of Iron Deficiency Anemia by Capsule Endoscopy.

Cureus 2022 May 22;14(5):e25208. Epub 2022 May 22.

Internal Medicine, Florida Atlantic University, Florida, USA.

Iron deficiency anemia (IDA) is a common medical condition that has numerous possible causes, which include reduced dietary intake, blood loss, or reduced absorption, and often results in a referral to a gastroenterologist for further work-up. Reduced absorption of iron is an uncommon cause of iron deficiency in healthy non-vegetarian individuals and resource-rich countries. We present an uncommon cause of IDA in the western hemisphere, secondary to Ascaris lumbricoides infection in a 65-year-old female without a history of travel to endemic regions. Read More

Higher helminth ova counts and incomplete decomposition in sand-enveloped latrine pits in a coastal sub-district of Bangladesh.

PLoS Negl Trop Dis 2022 Jun 23;16(6):e0010495. Epub 2022 Jun 23.

Department of Forestry and Environmental Resources, North Carolina State University, Raleigh, North Carolina, United States of America.

Pit latrines are the most common latrine technology in rural Bangladesh, and untreated effluent from pits can directly contaminate surrounding aquifers. Sand barriers installed around the latrine pit can help reduce contamination but can also alter the decomposition of the fecal sludge and accelerate pit fill-up, which can counteract their benefits. We aimed to evaluate whether there was a difference in decomposition of fecal sludge and survival of soil-transmitted helminth (STH) ova among latrines where a 50-cm sand barrier was installed surrounding and at the bottom of the pit, compared to latrines without a sand barrier, in coastal Bangladesh.

Affordable artificial intelligence-based digital pathology for neglected tropical diseases: A proof-of-concept for the detection of soil-transmitted helminths and Schistosoma mansoni eggs in Kato-Katz stool thick smears.

PLoS Negl Trop Dis 2022 Jun 17;16(6):e0010500. Epub 2022 Jun 17.

Janssen Global Public Health, Janssen R&D, Beerse, Belgium.

Background: With the World Health Organization's (WHO) publication of the 2021-2030 neglected tropical diseases (NTDs) roadmap, the current gap in global diagnostics became painfully apparent. Improving existing diagnostic standards with state-of-the-art technology and artificial intelligence has the potential to close this gap.

Methodology/principal Findings: We prototyped an artificial intelligence-based digital pathology (AI-DP) device to explore automated scanning and detection of helminth eggs in stool-based specimens prepared with the Kato-Katz (KK) technique, the current diagnostic standard for diagnosing soil-transmitted helminths (STHs; Ascaris lumbricoides, Trichuris trichiura and hookworms) and Schistosoma mansoni (SCH) infections.

Mapping the global distribution of Strongyloides stercoralis and hookworms by ecological niche modeling.

Parasit Vectors 2022 Jun 8;15(1):197. Epub 2022 Jun 8.

Instituto de Investigaciones de Enfermedades Tropicales (IIET), Sede Regional Orán Universidad Nacional de Salta, Salta, Argentina.

Background: The WHO has established a control strategy for Strongyloides stercoralis in school-aged children as well as targets and to maintain control programs for Ascaris lumbricoides, Trichuris trichiura and hookworms. For an efficient development of control programs, it is necessary to know the target countries around the world, as well as the areas within each country where efforts should be focused. Therefore, maps that provide information on the areas at risk for soil-transmitted helminth (STH) infections on a national and sub-national scale would allow for a better allocation of resources.

High infection rates for onchocerciasis and soil-transmitted helminthiasis in children under five not receiving preventive chemotherapy: a bottleneck to elimination.

Infect Dis Poverty 2022 Apr 28;11(1):47. Epub 2022 Apr 28.

Centre for Research on Filariasis and other Tropical Diseases (CRFilMT), Yaoundé, Cameroon.

Background: The current mainstay for control/elimination of onchocerciasis and soil-transmitted helminthiasis (STH) relies on ivermectin- and mebendazole/albendazole-based preventive chemotherapies. However, children under five years of age have been excluded in both research activities and control programs, because they were believed to have insignificant infection rates. There is therefore a need for up-to-date knowledge on the prevalence and intensity of STH and onchocerciasis infections in this age group. Read More
