Herpes simplex virus type-2 (HSV-2) has been identified as a possible aetiological agent of cancer in humans, especially prostate cancer, but results remain controversial. Here, we have addressed this question using a medical geography approach based on the national incidence of various cancers and seroprevalence of HSV-2 in 64 countries worldwide. We corrected reports of cancer incidence for national gross domestic product (GDP) because living in a wealthy nation likely increases the probability of having a cancer detected. Data were also corrected for latitude and diet. Our analysis not only confirms that prostate cancer and HSV-2 seroprevalence are positively associated, but it also reveals the existence of a positive relationship between HSV-2 and melanoma incidence in both men and women. These results, though correlational, suggest that HSV-2 should continue to be investigated as a possible oncogenic pathogen of humans. (C) 2011 Elsevier B.V. All rights reserved.

Molecular Characterization and Genetic Diversity of Haplogroup E Human Lice in Guinea, West Africa

Alissa Hammoud, Meriem Louni, Mamadou Cellou Balde, Abdoul Habib Beavogui, Philippe Gautret, Didier Raoult, Florence Fenollar, Dorothee Misse, Oleg Mediannikov

Summary: The majority of head lice belong to haplogroup E, with over 80% exhibiting the same gene polymorphism profile as body lice in haplogroup A. Some head lice were found to carry Acinetobacter pathogens, while sequencing revealed the presence of multiple Acinetobacter species. This study is the first to report the existence of the Guinean haplogroup E, the PHUM540560 gene polymorphisms profile, and the presence of Acinetobacter species in head lice collected from Guinea.

Chikungunya and Zika Viruses: Co-Circulation and the Interplay between Viral Proteins and Host Factors

Sineewanlaya Wichit, Nuttamonpat Gumpangseth, Rodolphe Hamel, Sakda Yainoy, Siwaret Arikit, Chuchard Punsawad, Dorothee Misse

Summary: Chikungunya and Zika viruses have globally re-emerged over the past 60 years and there is currently no specific antiviral treatment. Understanding viral-host interactions is crucial for developing targeted therapeutics, but limited information is available in this area at present.

Darwinian Approaches for Cancer Treatment: Benefits of Mathematical Modeling

Sophia Belkhir, Frederic Thomas, Benjamin Roche

Summary: The article discusses how mathematical models can help design alternative treatment strategies that take into account the ecology and evolution of tumors to avoid the emergence of resistance. Adaptive therapy is a promising anti-cancer treatment strategy that adjusts treatment cycles to control the population of treatment-resistant cells. Mathematical modeling is essential to understand cancer dynamics in response to treatments and to improve treatment outcomes with adaptive therapy strategies.

The 16S rRNA lung microbiome in mechanically ventilated patients: a methodological study

Melanie Fromentin, Antoine Bridier-Nahmias, Jerome Legoff, Severine Mercier-Delarue, Noemie Ranger, Constance Vuillard, Julien Do Vale, Noemie Zucman, Antonio Alberdi, Jean-Damien Ricard, Damien Roux

Summary: The accuracy of the bacterial lung microbiome composition is highly dependent on the primers used for amplification of the 16s rRNA hypervariable sequence. Comparing two different primer pairs, results show that S-V4 primer pair provides better agreement with conventional microbiology for respiratory samples compared to R-V4 primer pair.

Summary: Transmissible cancers are rare in the wild due to the specific conditions required for their emergence and spread. Further research is needed to identify the important factors that influence their occurrence and evolution.

Sea Turtles in the Cancer Risk Landscape: A Global Meta-Analysis of Fibropapillomatosis Prevalence and Associated Risk Factors

Antoine M. Dujon, Gail Schofield, Roberto M. Venegas, Frederic Thomas, Beata Ujvari

Summary: The study found that the prevalence of fibropapillomatosis in green turtles was highest in areas where nutrient concentrations facilitated toxic phytoplankton blooms, while ultraviolet light exposure and the presence of parasitic and symbiotic species did not appear to impact disease prevalence. Management actions to reduce eutrophication in foraging areas should be implemented to counter outbreaks of fibropapillomatosis.

Detection and genetic diversity of Mopeia virus in Mastomys natalensis from different habitats in the Limpopo National Park, Mozambique

Lourenco Mapaco, Laurent Crespin, Dercio Rodrigues, Joelle Gouy de Bellocq, Josef Bryja, Mathieu Bourgarel, Dorothee Misse, Alexandre Caron, Jose Fafetine, Julien Cappelle, Florian Liegeois

Summary: This study assessed the potential circulation and genetic diversity of mammarenaviruses in Mastomys natalensis trapped in the Limpopo National Park and its buffer zone in Massingir district, Mozambique. Results showed that Mopeia virus circulated widely in the study area and formed different sub-clusters.

Summary: This study conducted a longitudinal survey at two sites in Zimbabwe with bat-human interactions and found a high genetic diversity of bat coronaviruses. Different sub-viral groups were identified within the Alphacoronavirus and Betacoronavirus genus. The risk of bat coronavirus exposure for humans was found to be higher during certain months.

Impact of Fast SARS-CoV-2 Molecular Point-Of-Care Testing on Patients' Length of Stay in an Emergency Department

Audrey Baron, Olivier Peyrony, Maud Salmona, Nadia Mahjoub, Sami Ellouze, Maud Anastassiou, Constance Delaugerre, Jean-Paul Fontaine, Sylvie Chevret, Jerome LeGoff, Linda Feghoul

Summary: The use of the ID NOW COVID-19 system in an emergency department was found to significantly reduce the length of stay for patients. The implementation of molecular point-of-care testing for SARS-CoV-2 resulted in faster results and decreased overcrowding in the emergency department. This study emphasizes the importance and benefits of COVID-19 molecular point-of-care testing in preventing overcrowding and facilitating patient care and isolation.

Internal RNA 2′O-methylation in the HIV-1 genome counteracts ISG20 nuclease-mediated antiviral effect

Priscila El Kazzi, Nadia Rabah, Celia Chamontin, Lina Poulain, Francois Ferron, Francoise Debart, Bruno Canard, Dorothee Misse, Bruno Coutard, Sebastien Nisole, Etienne Decroly

Summary: This study reveals that the 2' O-methylation marks inside the HIV-1 genome help the virus evade the host immune system. The virus achieves self-methylation by recruiting the cellular methyltransferase FTSJ3, which allows it to avoid detection by the antiviral protein ISG20. This mechanism enables HIV-1 to replicate and spread more effectively.

Summary: Coronaviruses are a group of viruses that infect various animals, including humans. This study aimed to detect coronaviruses in wild great apes and mandrills in Gabon. However, no coronaviruses were found in the fecal samples collected from 2009 to 2012. Further research is needed to investigate the presence of coronaviruses in these primates.
