Long-term 4CMenB Vaccine Effectiveness Against Gonococcal Infection at Four Years Post-Program Implementation: Observational Case-Control Study.

Background: A 4-component meningococcal B (4CMenB) vaccine program was introduced in adolescents in 2019 in South Australia. We aimed to evaluate long-term vaccine effectiveness (VE) and impact (VI) on gonococcal infection 4 years after implementation of the program.

Methods: Disease notification data were provided by SA Health.

Longitudinal strain enhancement and bending deformations in piezoceramics.

Piezoelectric materials directly convert between electrical and mechanical energies. They are used as transducers in applications such as nano-positioning and ultrasound imaging. Improving the properties of these devices requires piezoelectric materials capable of delivering a large longitudinal strain on the application of an electric field.

The Impact of Obesity on Influenza Vaccine Immunogenicity and Antibody Transfer to the Infant During Pregnancy.

Background/objectives: Influenza vaccination is recommended for pregnant women, offering the dual benefit of protecting pregnant women and their newborn infants against influenza. This study aimed to investigate the impact of body mass index (BMI) on influenza vaccine responses in pregnant women and their newborns.

Methods: Participants included pregnant women attending the Women's and Children's Hospital in South Australia between 2018 and 2021.

The role of prenatal perceived stress and hair cortisol as they relate to toddler socioemotional outcomes over the first three years.

Prenatal maternal psychological distress and physiological stress (hypothalamic-pituitary-adrenal [HPA] activity) can negative impact early child development. Research rarely examines the combined or interactive role of prenatal perceived stress and HPA activity on child outcomes. The current longitudinal study examined how prenatal distress and HPA activity impacted child socioemotional functioning from age 1-3.

Outcomes of 584 cattle caesarean sections performed in a UK first opinion practice.

Background: This retrospective cohort study evaluated 584 cattle caesarean sections (C-sections) performed at a first opinion practice in Southwest England between 2015 and 2021.

Methods: Outcomes were recorded contemporaneously, and procedures were followed up after 14 days.

Results: Thirty-one dams died within 14 days of undergoing a C-section (94.
