A metagenomics method for the quantitative detection of bacterial pathogens causing hospital-associated and ventilator-associated pneumonia.

The management of ventilator-associated pneumonia and hospital-acquired pneumonia requires rapid and accurate quantitative detection of the infecting pathogen. To this end, we propose a metagenomic sequencing assay that includes the use of an internal sample processing control for the quantitative detection of 20 relevant bacterial species from bronchoalveolar lavage samples.

Comparison of DNA extraction methods for 16S rRNA gene sequencing in the analysis of the human gut microbiome.

The gut microbiome is widely analyzed using high-throughput sequencing, such as 16S rRNA gene amplicon sequencing and shotgun metagenomic sequencing (SMS). DNA extraction is known to have a large impact on the metagenomic analyses. The aim of this study was to compare DNA extraction protocols for 16S sequencing.

Contribution of Clinical Metagenomics to the Diagnosis of Bone and Joint Infections.

Bone and joint infections (BJIs) are complex infections that require precise microbiological documentation to optimize antibiotic therapy. Currently, diagnosis is based on microbiological culture, sometimes complemented by amplification and sequencing of the 16S rDNA gene. Clinical metagenomics (CMg), that is, the sequencing of the entire nucleic acids in a sample, was previously shown to identify bacteria not detected by conventional methods, but its actual contribution to the diagnosis remains to be assessed, especially with regard to 16S rDNA sequencing.

Meralgia Paresthetica Successfully Treated with Palmithoylethanolamide.

Meralgia paresthetica (MP) is an uncommon entrapment mononeuropathy that is characterized by a sudden onset of paresthesia and numbness in the anterolateral surface of the thigh. Palmithoylethanolamide (PEA) is commonly used in the treatment of chronic pelvic pain and compressive neuropathies. Herein, we describe an otherwise healthy 28-year-old patient affected by posttraumatic MP for three months who was successfully treated with PEA (1200mg/day).
