Lymphatic filariasis

The impact of podoconiosis, lymphatic filariasis, and leprosy on disability and mental well-being: A systematic review

Oumer Ali et al.
PLOS Neglected Tropical Diseases
The objective of this systematic review was to synthesize the existing evidence describing the disability, psychosocial, and mental health status of people affected by leprosy, podoconiosis, and LF prior to developing a holistic physical and psychosocial care package for these individuals. . . Following this review, we are working on the development of a holistic integrated care package for people affected by leprosy, podoconiosis, and LF in northwestern Ethiopia.

Comparison of Immunochromatographic Test (ICT) and Filariasis Test Strip (FTS) for Detecting Lymphatic Filariasis Antigen ...

Meru Sheel, Colleen L. Lau, Sarah Sheridan, Saipale Fuimaono and Patricia M. Graves
Tropical Medicine and Infectious Disease
In 2016,we conducted lymphatic filariasis surveys in American Samoa using FTS, which found higher Ag prevalence than previous surveys that used ICT. . . Based on these findings, if ICT had been used in the 2016 surveys, the results and interpretation would have been similar to those reported using FTS.

Schistosomiasis

Population Pharmacokinetics of Praziquantel in Pregnant and Lactating Filipino Women Infected with Schistosoma japonicum

Amaya Bustinduy et al.
Antimicrobial Agents and Chemotherapy
As part of a randomized controlled trial investigating the safety and efficacy of PZQ during human pregnancy, we examined the PK of this therapeutic drug among three distinct cohorts of women infected with S. japonicum in Leyte, Philippines.

Transposable Elements in the Genome of Human Parasite Schistosoma mansoni: A Review

Gisele Strieder Philippsen
Tropical Medicine and Infectious Disease
In this context, the literature concerning TEs [Transposable elements] description and TEs impact on the genomic architecture for S. mansoni was revisited, displaying evidence of TEs influence on schistosome speciation—mediated by bursts of transposition—and in gene-duplication events related to schistosome–host coevolution processes, as well several instances of TEs contribution into the coding sequences of genes. These findings indicate the relevant role of TEs in the evolution of the S. mansoni genome.

Merck KGaA, Darmstadt, Germany, and Universal Agree on Contract Manufacturing for new Pediatric Medication Against Schistosomias

Timo Breiner
Merck KGaA
Merck KGaA, Darmstadt, Germany, a leading science and technology company, has entered into a contract manufacturing agreement with Universal Corporation Ltd., Nairobi, Kenya, a subsidiary of Strides Pharma Science Limited, India, for the large-scale production of a new pediatric medication. Production will begin once the medication has been registered. The drug is needed to treat the neglected tropical disease (NTD) schistosomiasis in preschool-aged children younger than six and is currently in late-stage development.

Soil-Transmitted Helminthiasis

Evaluating Equity and Coverage in Mass Drug Administration for Soil-Transmitted Helminth Infections among School-Age Children ..

Asfaw MA, Hailu C and Beyene TJ
Pediatric Health, Medicine and Therapeutics
The very low (27.5%) and inequitable MDA coverage found in this study are associated with school nonenrollment, inaccessibility, and lack of information, awareness, and mobilization. Social mobilization should be scaled up to inform and create awareness in the community ahead of MDA.

The prevalence of tuberculosis, malaria and soil-transmitted helminth infection in minority indigenous people of Southeast Asia

Beth Gilmour, Kefyalew Addis Alene, Naomi E. Clarke and Archie C. A. Clements
Systematic Reviews
This systematic review aims to analyse the available data on the prevalence of TB, malaria and STH infections within minority indigenous populations of the SEAR and WPR.

Transmission of Soil Transmitted Helminthiasis in the Mifi Health District (West Region, Cameroon): Low Endemicity ...

Laurentine Sumo, Esther Nadine Otiobo Atibita, Eveline Mache, Tiburce Gangue and Hugues C. Nana-Djeunga
Parasitologia
These results are supportive of the low endemicity level of STHs in the Mifi Health District, but environmental pollution by dissemination stages of the parasites outlines that the risk of transmission is still persistent. It therefore appears compulsory to account for the environment when considering policy/recommendations for transmission interruption and stopping MDA, as it is in the case with vector-borne diseases.

Trachoma

World’s Largest Trachoma Surveys Reach 50th Country

Sightsavers
The world’s largest surveys into infectious disease have reached an important milestone, with Sierra Leone becoming the 50th country to be surveyed for trachoma as part of the initiative. The series of surveys began as the Global Trachoma Mapping Project, later becoming the Tropical Data collaboration. On average one person has been examined for trachoma every 26 seconds since the surveys began in 2012.

Empowering Maasai women behind the camera: Photovoice as a tool for trachoma control

Tara B. Mtuy, Jeremiah Mepukori, Joseph Lankoi and Shelley Lees
Research Involvement and Engagement
Photovoice should be considered for future interventions as a communication tool on health issues and to empower women to be ambassadors for health promotion.

Stopping azithromycin mass drug administration for trachoma: A systematic review

Hamidah Mahmud et al.
PLOS Neglected Tropical Diseases
Our systematic review finds that ocular chlamydia infection may return to communities faster than signs of active trachoma, which may help better understand the utility of different trachoma indicators for post-MDA surveillance.

Knowledge, Attitude, Practices and Associated Factors Towards Trachoma Among People Living in Arba Minch Zuria District ...

Chuchu Churko, Mekuria Asnakew Asfaw and Zerihun Zerdo
Clinical Ophthalmology
Considerable numbers of people have unfavorable attitude and inadequate knowledge about trachoma infection. Awareness creation through community mobilization and sensitization should be strengthened.

Towards an odour-baited trap to control Musca sorbens, the putative vector of trachoma

Ailie Robinson et al.
Scientific Reports
We tested commercially available and homemade trap types in a pilot (laboratory) study and three field studies. . . The Buzz lure is cheap and effective for 4 weeks, and trap components cheap and locally available. Further studies are needed to understand the impact of this trap on local fly populations and the local transmission of trachoma.

But the good news is that when they come and undergo the operation, they live in society again, ”explains Samuel Joseph, a nurse from Doctors Without Borders (MSF) who accompanies patients in their process from the moment they arrive at the center. sanitary until they leave it, already recovered. After the intervention, many of them can breathe well again, regain full mobility of the mouth and are no longer the target of everyone’s gaze for their disfigured face.
