Thematic analysis was used to extract themes.Results: Twenty-four people were interviewed. The participants exhibited inadequate knowledge about C. sinensis infection and were unaware of the health risks. Although some have reduced their consumption of raw fish, some continue to consume it frequently. Compared with stopping eating raw fish, receiving tests and taking medicines were easier behaviours to adopt. Guided by the SCT, we considered the reciprocal determinism between people and the social environment as the basis of the persistent raw fish consumption behaviour. While the social environment could influence the cognition and behaviours of people, people also can reshape the social environment. Based on the reciprocal determinism, we proposed an integrated intervention framework.Conclusions: Our study unveiled a reciprocal determinism between the cognition, behaviours and social environment related to C. sinensis infection in high-endemic areas of China, providing insights for establishing control strategies.","PeriodicalId":23218,"journal":{"name":"Transactions of The Royal Society of Tropical Medicine and Hygiene","volume":" ","pages":"479-486"},"PeriodicalIF":1.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142877971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pulmonary haemorrhages are a deadly complication, with case fatality rates >50%. Systemic vasculitis is thought to be the pathological process responsible for pulmonary haemorrhages and therapeutic plasma exchange (TPE) is one of the treatments offered. This systematic review aims to evaluate the effectiveness of TPE in managing leptospirosis-associated severe pulmonary haemorrhagic syndrome (SPHS). A systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis protocol. The search used Medical Subject Headings in PubMed with keywords 'Leptospirosis' OR 'Leptospira' OR 'Weil disease' AND 'plasmapheresis' OR 'plasma exchange' AND 'pulmonary haemorrhage' OR 'alveolar haemorrhage'. The search was widened to include the Google Scholar database. The review was confined to English-language articles and focused on primary research studies. Nineteen articles were considered for analysis. There were no randomized controlled trials. A non-randomized trial and a retrospective cohort documented recovery following adjuvant TPE treatment. Most case reports mention significant improvement and complete recovery following administration of TPE. One case reported the death of a patient despite treatment. However, this review revealed a lack of strong evidence endorsing the routine application of TPE as a therapeutic intervention for cases of SPHS. Thus we recommend the initiation of a well-structured randomized controlled trial to ensure an accurate assessment of the efficacy of TPE.","PeriodicalId":23218,"journal":{"name":"Transactions of The Royal Society of Tropical Medicine and Hygiene","volume":" ","pages":"453-463"},"PeriodicalIF":1.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142688748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These infections are spread by mosquito species such as Culex, Anopheles, Aedes and Mansonia. With >50 million cases in 44 countries, it is the most important parasitic disease next to malaria. India initiated a mass drug administration (MDA) program in 2004 and a gradual reduction was seen in the cases; however, few pockets continue to record new cases. We conducted this study in Datia district of Madhya Pradesh, known to be endemic for filariasis, to understand the ongoing transmission and vector incrimination.Methods: Mosquitoes were collected from rural and urban localities of Datia district. Mosquitoes were identified, segregated and pooled. The pools were tested for the presence of W. bancrofti using molecular tools. The polymerase chain reaction (PCR) products were sequenced for confirmation of results.Results: Of 974 tested female mosquitoes, 45.8% were Culex quinquefasciatus and 50.8% were Anopheles subpictus. The mosquitoes were segregated in 55 pools; 8 (14.54%) pools were found positive for W. bancrofti by real-time PCR. All the positive pools were of C. quinquefasciatus and the species-specific pool positivity rate was 24.24%. All the positive pools were from Sarsai village. The sequencing results confirmed the presence of W. bancrofti.Conclusions: This study confirms ongoing transmission of W. bancrofti and C. quinquefasciatus as the vector species in the rural parts of district. The intervention protocols such as MDA and vector control activities need to be strengthened in rural parts of endemic districts to halt the transmission.","PeriodicalId":23218,"journal":{"name":"Transactions of The Royal Society of Tropical Medicine and Hygiene","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144062157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study on dengue hospitalised patients compares haematocrit levels at baseline, at the onset of the critical phase and the maximum during the critical phase in rural Sri Lanka.Methods: This observational study included patients with dengue in the febrile phase who progressed to the critical phase. Haematocrit was recorded and ultrasound scans were performed thrice daily when the platelet count dropped to <100 000/μl. The onset of the critical phase was confirmed by ultrasound-detected plasma leakage.Results: Forty-three patients were included in the final analysis. The mean haematocrit at baseline and at the onset of the critical phase was 40.6% (standard deviation [SD] 4.7) and 41.3% (SD 5.1), respectively, with no difference (p=0.14, paired t-test). None of the participants showed a 20% increase in haematocrit at the onset of the critical phase, with the maximum observed increase being 17.0%.Conclusion: A 20% increase in haematocrit was not observed during the critical phase, suggesting that haemoconcentration is unreliable for diagnosing DHF in hospitalised patients. This study recommends revisiting the WHO criterion of a 20% haematocrit increase for diagnosing plasma leakage in dengue patients. It suggests that frequent ultrasound scans may be a more reliable method for early detection of plasma leakage.","PeriodicalId":23218,"journal":{"name":"Transactions of The Royal Society of Tropical Medicine and Hygiene","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144024809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While concentrated on the 'Big Four' venomous species, recent research indicates a necessity to expand the focus to encompass additional medically relevant species. This review emphasizes the geographic heterogeneity in venom among these snakes, which impacts antivenom effectiveness and necessitating region-specific formulations. This analysis highlights the shortcomings of current antivenoms and identifies non-Big Four species involved in snakebite envenoming, advocating for an urgent shift to inclusive antivenom strategies that integrate local venom profiles to enhance treatment effectiveness and thereby reduce snakebite-related morbidity and mortality. Improved training for healthcare providers and enhancements in anti-snake venom quality are essential for meeting the World Health Organization's 2030 Sustainable Development Goal objective of halving snakebite-related fatalities and disabilities. Incorporating snakebite management into national health programs and conducting epidemiological research systematically are crucial to mitigating this preventable health concern.","PeriodicalId":23218,"journal":{"name":"Transactions of The Royal Society of Tropical Medicine and Hygiene","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144039228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
