The effect of COVID-19 fear on prenatal distress and childbirth preference in primipara.
The purpose of this study was to examine the effect of COVID-19 fear on prenatal distress and childbirth preference in primipara. ⋯ It was determined that fear of coronavirus increases prenatal distress. Women should be supported to cope with fear of COVID-19 and prenatal distress, both during the preconceptional and antenatal periods.

Perceptions of the Brazilian obstetrics physicians about the term obstetric violence: a cross-sectional study.
We observe a growing global discussion about the practices considered "obstetric violence" against women during pregnancy and childbirth. Otherwise, the indiscriminate subjective and lay interpretation of the term "obstetric violence" can lead to a misunderstanding among medical professionals. ⋯ We observed that almost three in four obstetrician participants consider the term "obstetric violence" nocive or harmful to professional practice, particularly in those who graduated before 2000 and from a private institution. The findings are relevant to propose further debates and strategies to mitigate the possible harms caused to the obstetrician team by the indiscriminate use of the term obstetric violence.

Evaluation of toxin-antitoxin genes, antibiotic resistance, and virulence genes in Pseudomonas aeruginosa isolates.
Toxin-antitoxin genes RelBE and HigBA are known to be involved in the formation of biofilm, which is an important virulence factor for Pseudomonas aeruginosa. The purpose of this study was to determine the presence of toxin-antitoxin genes and exoenzyme S and exotoxin A virulence genes in P. aeruginosa isolates and whether there is a relationship between toxin-antitoxin genes and virulence genes as well as antibiotic resistance. ⋯ The findings suggest that antibiotic resistance may be linked to toxin-antitoxin genes. Furthermore, the relationship between RelBE and exoenzyme S indicates that toxin-antitoxin genes in P. aeruginosa isolates are not only related to antibiotic resistance but also play an influential role in bacterial virulence. Larger collections of comprehensive studies on this subject are required. These studies should contribute significantly to the solution of the antibiotic resistance problem.

miR-21, miR-221, and miR-222 upregulation in lung cancer promotes metastasis by reducing oxidative stress and apoptosis.
The purpose of our research was to observe the effects of miR-21, miR-221, and miR-222, as well as their target genes on oxidative stress, lung cancer formation, and metastasis. ⋯ Our findings show that upregulation of hsa-miR-21-5p, hsa-miR-221-3p, and hsa-miR-222-3p effectively contributes to both proliferation and invasion by influencing oxidative stress and mitochondrial apoptosis.

Blood group as a novel predictor of postoperative atrial fibrillation after off-pump coronary artery bypass grafting.
The objective of this study was to reveal whether there was a possible relationship between the blood group and postoperative atrial fibrillation after off-pump coronary artery bypass grafting. ⋯ We demonstrated for the first time in the literature that ABO blood type was a novel and significant predictor of new-onset atrial fibrillation after off-pump coronary artery bypass grafting.
