The background of Helicobacter pylori (H. pylori) infection is complex, and its influence on adverse pregnancy outcomes is inconsistently reported. We performed a multi-institutional, retrospective analysis using de-identified electronic health records from the TriNetX Research Network to compare various pregnancy outcomes in women with and those without H.

The number of cationic residues and net charge are critical for the activity of antimicrobial peptides (AMPs) due to their role in facilitating initial electrostatic interactions with negatively charged bacterial membranes. A cathelicidin AMP (TC-33) has been identified from the Chinese tree shrew in our previous work, which exhibited weak antimicrobial activity, likely due to its moderately cationic nature. In the current study, based on TC-33, we designed a novel AMP by peptide truncation and Glu substitutions to increase its net cationic charge from +4 to +8.

Article Synopsis
  • - The study explores how tweaking the structure of antimicrobial peptides (AMPs) by disrupting their amphipathicity can improve their selectivity and efficacy against bacteria.
  • - The lead peptide, RI-18, showed strong antibacterial properties without causing harm to human cells, effectively targeting both free-floating and biofilm-associated bacteria.
  • - By tuning the characteristics of AMPs like RI-18, researchers aim to develop more effective treatments that combat bacterial infections without causing resistance.

Dry eye disease (DED) is associated with ocular hyperosmolarity and inflammation. The marketed topical eye drops for DED treatment often lack bioavailability and precorneal residence time. In this study, we investigated catechol-functionalized polyzwitterion p(MPC-co-DMA), composed of 2-methacryloyloxyethyl phosphorylcholine (MPC) and dopamine methacrylamide (DMA) monomers, as potential topical nanotherapeutics for DED.

The quality of healthcare is crucially linked to patient satisfaction, particularly in the provision of neuraxial analgesia for labor pain. Neuraxial analgesia for labor pain control should ideally be readily available when requested. However, in real-world practice, anesthesiologists may not always respond immediately to maternal demands, which can compromise the quality of care.

Historically known as a "silent killer", ovarian cancer is often diagnosed at an advanced stage. We describe an unusual case of stage I, ovarian, high-grade serous carcinoma detected by a routine Papanicolaou (PAP) smear, with no abnormal physical, imaging, or laboratory findings. A 53-year-old woman with newly diagnosed triple-negative breast cancer received a screening Pap smear, which showed malignant cells not coming from the breast or uterine cervix.
