Professional support to enhance the early parent-infant relationship in the first months after birth is recommended, but little is known about the effect of universal interventions. The objective was to investigate the effect of health visitors' use of the Newborn Behavioral Observations system in new families. A cluster-randomised study was conducted in four Danish municipalities. Health visitors' geographical districts constituted the units for randomisation (n = 17). In the intervention group, 1332 families received NBO from 3 weeks after birth; in the comparison group, 1234 received usual care. Self-administered questionnaires were collected at baseline one to two weeks after birth, and at follow-up three and nine months postpartum. The outcomes were change over time measured by The Karitane Parenting Confidence Scale (KPCS), The Major Depression Inventory (MDI), The Ages and Stages Questionnaire social-emotional (ASQSE) and The Mother and Baby Interaction Scale (MABIC).

Porphyromonas gingivalis (Pg) infection causes periodontal disease and exacerbates rheumatoid arthritis (RA). It is reported that inoculation of periodontopathogenic bacteria (i.e., Pg) can alter gut microbiota composition in the animal models. Gut microbiota dysbiosis in human has shown strong associations with systemic diseases, including RA, diabetes mellitus, and inflammatory bowel disease. Therefore, this study investigated dysbiosis-mediated arthritis by Pg oral inoculation in an experimental arthritis model mouse. Pg inoculation in the oral cavity twice a week for 6 weeks was performed to induce periodontitis in SKG mice. Concomitantly, a single intraperitoneal (i.p.) injection of lami
