Hepatolithiasis: Epidemiology, presentation, classification and management of a complex disease
World J Gastroenterol. 2024 Apr 7;30(13):1836-1850. doi: 10.3748/wjg.v30.i13.1836.ABSTRACTThe term hepatolithiasis describes the presence of biliary stones within the intrahepatic bile ducts, above the hilar confluence of the hepatic ducts. The disease is more prevalent in Asia, mainly owing to socioeconomic and dietary factors, as well as the prevalence of biliary parasites. In the last century, owing to migration, its global incidence has increased. The main pathophysiological mechanisms involve cholangitis, bile infection and biliary strictures, creating a self-sustaining cycle that perpetuates the disease, frequently c...

Streptococcus pneumoniae endopeptidase O induces trained immunity against numerous pathogen infections, a key role for G-CSF
Clin Immunol. 2024 Apr 23:110226. doi: 10.1016/j.clim.2024.110226. Online ahead of print.ABSTRACTAntibiotic resistance and the surge of infectious diseases during the pandemic present significant threats to human health. Trained immunity emerges as a promising and innovative approach to address these infections. Synthetic or natural fungal, parasitic and viral components have been reported to induce trained immunity. However, it is not clear whether bacterial virulence proteins can induce protective trained immunity. Our research demonstrates Streptococcus pneumoniae virulence protein PepO, is a highly potent trained immun...

Anti-Anisakis antibodies in colon cancer patients and their relationship with γδ T-cells
Parasitol Res. 2024 Apr 25;123(4):196. doi: 10.1007/s00436-024-08216-y.ABSTRACTMany pathogens are related to carcinogenesis. Chronic inflammation, as a result of persistent infection, leads to DNA damage, higher expression of oncogenes, decreased apoptosis and immunosuppression, which are some of the reasons for cancer induction. Among parasites, Schistosoma, Opistorchis and Clonorchis are recognised as infectious agents which contribute to cancer. A relationship between Anisakis and cancer was hypothesised because cellular responses to Anisakis products could result in inflammation and DNA damage. Previous research has sh...

Transcript tinkering: RNA modifications in protozoan parasites
Curr Opin Microbiol. 2024 Apr 24;79:102477. doi: 10.1016/j.mib.2024.102477. Online ahead of print.ABSTRACTApicomplexan and trypanosomatid parasites have evolved a wide range of post-transcriptional processes that allow them to replicate, differentiate, and transmit within and among multiple different tissue, host, and vector environments. In this review, we highlight the recent advances that point toward the regulatory potential of RNA modifications in mediating these processes on the coding and noncoding transcriptome throughout the life cycle of protozoan parasites. We discuss the recent technical advancements enabling t...

Intricate balance of dually-localized catalase modulates infectivity of Leptomonas seymouri (Kinetoplastea: Trypanosomatidae)
Int J Parasitol. 2024 Apr 23:S0020-7519(24)00077-8. doi: 10.1016/j.ijpara.2024.04.007. Online ahead of print.ABSTRACTNearly all aerobic organisms are equipped with catalases, powerful enzymes scavenging hydrogen peroxide and facilitating defense against harmful reactive oxygen species. In trypanosomatids, this enzyme was not present in the common ancestor, yet it had been independently acquired by different lineages of monoxenous trypanosomatids from different bacteria at least three times. This observation posited an obvious question: why was catalase so "sought after" if many trypanosomatid groups do just fine without it...

A prevalence study on gastrointestinal parasitic infections of pig (Sus scrofa) in and around Meerut, Western Uttar Pradesh, India
AbstractThe present study was conducted to record the prevalence of gastrointestinal parasites of pigs by faecal sample examination. Faecal samples were collected in three different seasons viz; monsoon, post monsoon and pre monsoon, from in and around Meerut district of Western Uttar Pradesh. A total of 642 faecal samples were collected for a period of one year (2020 –21). The overall prevalence rate recorded for gastrointestinal parasites in pigs was 64.4%.The findings of the present work showed that seasons have a significant role on the prevalence of gastrointestinal parasites infection in pigs, with highest prevalen...

Sampling is decisive to determination of < i > Leishmania (Viannia) < /i > species
ConclusionsThe type of clinical sample can directly influence the detection and identification ofLeishmania (Viannia) species. Here, we demonstrated that lancet scraping samples consistently allowed the identification of more leishmaniasis cases compared to filter paper imprints or biopsies. This procedure is inexpensive, painless, and easy to implement at the point of care and avoids the need for anesthesia, surgery, and hospitalization and therefore could be used in resource limited settings for both military and civilian populations.

Spatio-temporal distribution of hospitalizations for chronic Chagas disease and risk factors associated with in-hospital mortality and surgical intervention in Chile
by Nicolhole Atero, Marisa Torres, Ang élica Domínguez, Benjamín Diethelm-Varela, Francisca Córdova-Bührle, Fernando O. Mardones Chagas disease (CD) is a neglected parasitic zoonotic disease that affects over 6 million people worldwide. We conducted a retrospective study to analyze the spatiotemporal trends and risk factors for hospitalization rates of CD with cardiac and digestive diagnoses in Chile. We used the Mann-Kendall analysis for temporal trends, Global Moran ’s Index, and Local Indicators of Spatial Association to identify spatial autocorrelation, and regression models to determine the risk factors associ...

Ancestral aneuploidy and stable chromosomal duplication resulting in differential genome structure and gene expression control in trypanosomatid parasites [RESEARCH]
Aneuploidy is widely observed in both unicellular and multicellular eukaryotes, usually associated with adaptation to stress conditions. Chromosomal duplication stability is a tradeoff between the fitness cost of having unbalanced gene copies and the potential fitness gained from increased dosage of specific advantageous genes. Trypanosomatids, a family of protozoans that include species that cause neglected tropical diseases, are a relevant group to study aneuploidies. Their life cycle has several stressors that could select for different patterns of chromosomal duplications and/or losses, and their nearly universal use o...
