Clinical and laboratory profile of Expanded Dengue Syndrome: experience of 2019 outbreak from Dhaka, Bangladesh
CONCLUSION: In the year 2019, an unusual rise in EDS cases with about 15.4% fatalities were observed in this study. Hepatitis was the most common presentation and cause of death. Here, we report the first ARDS case encountered in Bangladesh. Despite the multifaceted presentation of EDS, indiscriminate use of antibiotics and steroid was minimal. Early recognition of multifarious features of EDS is important for choosing the targeted treatment option which can avert many deaths. The results of this study underline the necessity for more in-depth research into the risk factors that are contributing to mortality in EDS cases.P...

Evaluation of Insect Growth Regulators (IGRs) as biological pesticides for control of Aedes aegypti mosquitoes
CONCLUSION: None of the IGRs was more effective at the pupal stage but showed carry-on activity of growth inhibition and mortality of the successive stages of development when used against eggs stages. Therefore, we recommend early application of IGRs at mosquito habitats during the beginning and onset of the season when very early stages of mosquitoes are available in the field.PMID:38648415 | DOI:10.4103/0972-9062.392257 (Source: Journal of Vector Borne Diseases)

Entomological assessment in 'hotspots' of four lymphatic filariasis endemic districts, Central Nepal during post-MDA surveillance
CONCLUSION: We conclude that the gravid trap is an efficient tool for the collection of gravid Cx. quinquefasciatus mosquitoes for xenomonitoring studies of filariasis endemic regions. Vector composition indicated a maximum number of vector mosquitoes of lymphatic filariasis were trapped compared with the other three species. Distribution and density of Cx. quinquefasciatus was found highest in four hotspots of endemic districts. None of the Cx. quinquefasciatus dissected were found to be infected by larval forms of filaria. Since the low levels of infection persistence in the human population in these hot spots, vector in...

Toxicity of Trixis vauthieri DC essential oil on Lutzomyia longipalpis (Diptera, Psychodidae, Phlebotominae), a proven vector of visceral leishmaniasis in Brazil
CONCLUSION: The results obtained suggest that T. vauthieri essential oil is fairly promising as an insecticidal potential against L. longipalpis. A more detailed analysis of the oil's phytochemical composition is necessary to identify active and pure compounds that can be used in vector control of visceral leishmaniasis.PMID:38648417 | DOI:10.4103/0972-9062.383642 (Source: Journal of Vector Borne Diseases)

Nanotechnology and malaria: Evaluation of efficacy and toxicity of green nanoparticles
J Vector Borne Dis. 2024 Apr 12. doi: 10.4103/JVBD.JVBD_175_23. Online ahead of print.ABSTRACTMalaria is a global health problem that causes 1.5-2.7 million deaths worldwide each year. Resistance to antimalarial drugs in malaria parasites and to insecticides in vectors is one of the most serious issues in the fight against the disease. Moreover, the lack of an effective vaccine against malaria is still a major concern. Recent developments in nanotechnology have resulted in new prospects for the fight against malaria, especially by obtaining metal nanoparticles (NPs) that are less toxic, highly biocompatible, environmentall...

Dengue dynamics: Prognostic and disease monitoring through molecular and serological profiling of clinical isolates
CONCLUSION: Our laboratory effectively standardized an RT-PCR-based approach for molecular identification of dengue virus in clinical specimens. This adaptive technique which used numerous primer sets displayed good specificity and sensitivity in serotype detection. The technology provides for quick and reliable identification of dengue virus infections, allowing for targeted treatment and preventative actions for successful disease management in highly populated regions.PMID:38634367 | DOI:10.4103/JVBD.JVBD_202_23 (Source: Journal of Vector Borne Diseases)

Social, behavioral and environmental determinants of vector-borne diseases: A narrative review of evidence and implications for integrated control approaches
J Vector Borne Dis. 2024 Apr 18. doi: 10.4103/JVBD.JVBD_34_24. Online ahead of print.ABSTRACTVector-borne diseases exert immense health burdens worldwide. Malaria alone causes over 200 million cases and 600,000 deaths annually. Transmission involves complex drivers requiring examination beyond entomological factors. A systematic literature search across databases identified relevant studies on vector-borne disease determinants published in the last two decades, with priority given to rigorous designs like longitudinal analyses, reviews, and meta-analyses from diverse epidemic regions, allowing narrative synthesis of key de...

Bioacoustics in population control of insects of medical importance: A review
J Vector Borne Dis. 2024 Apr 12. doi: 10.4103/JVBD.JVBD_204_23. Online ahead of print.ABSTRACTVector transmitted diseases are accountable for more than 17% of all infectious disease cases worldwide according to World Health Organization. Insect vectors play a key role in transmitting diseases and loss of lives. Modified and advanced vector control strategies with chemical insecticides are needed as vectors are resistant to a particular insecticide. Moreover, chemical control is cost-inductive and may give rise to health issues. In this review, bioacoustics have been narrated as a novel technology for eco-friendly and cost-...

A comparative study on vector competence of Anopheles stephensi from geographically distinct malarious and a non-malarious urban area to Plasmodium vivax
CONCLUSION: An. stephensi of Chennai and Coimbatore are equally susceptible to P. vivax infection and non-transmission of malaria in Coimbatore can be attributed to external factors such as the presence of preferential breeding habitat, vector density, vector survival, and weather. The only difference observed was the comparatively shortened oocyst maturation time in the Coimbatore strain which requires further investigation.PMID:38634456 | DOI:10.4103/JVBD.JVBD_7_24 (Source: Journal of Vector Borne Diseases)
