The Predictive Factors Associated with In-Hospital Mortality of Melioidosis: A Cohort Study
Conclusions: Our study identified age, respiration rate, abnormal chest X-ray finding, and CO2 levels are predictive factors associated with in-hospital mortality in melioidosis patients. Physicians should be aware of these factors, have access to aggressive treatment options, and closely monitor patients with these risk factors.PMID:38674300 | PMC:PMC11052379 | DOI:10.3390/medicina60040654 (Source: Medicina (Kaunas))

A comparative assessment of microbiocenosis of saliva and oropharynx in patients with migraine
CONCLUSION: A comparative assessment of the microbiota of a smear from the posterior wall of the oropharynx and saliva using MMSM showed the presence of dysbiosis both in the oropharynx and in the saliva of patients with migraine. However, there were fewer deviations from the norm in saliva, therefore, for diagnostic purposes, a smear from the posterior wall of the oropharynx is more significant as a biomarker for patients with migraine.PMID:38676678 | DOI:10.17116/jnevro202412404155 (Source: Herpes)

Phage transmission strategies: are phages farming their host?
Curr Opin Microbiol. 2024 Apr 26;79:102481. doi: 10.1016/j.mib.2024.102481. Online ahead of print.ABSTRACTExtensive coevolution has led to utterly intricate interactions between phages and their bacterial hosts. While both the (short-term) intracellular molecular host-subversion mechanisms during a phage infection cycle and the (long-term) mutational arms race between phages and host cells have traditionally received a lot of attention, there has been an underestimating neglect of (mid-term) transmission strategies by which phages manage to cautiously spread throughout their host population. However, recent findings unders...
