Low-dose betamethasone-acetate for fetal lung maturation in preterm sheep
BackgroundAntenatal steroids are standard of care for women who are at risk of preterm delivery; however, antenatal steroid dosing and formulation have not been evaluated adequately. The standard clinical 2-dose treatment with betamethasone-acetate+betamethasone-phosphate is more effective than 2 doses of betamethasone-phosphate for the induction of lung maturation in preterm fetal sheep. We hypothesized that the slowly released betamethasone-acetate component induces similar lung maturation to betamethasone-phosphate+betamethasone-acetate with decreased dose and fetal exposure.ObjectiveThe purpose of this study was to investigate pharmacokinetics and fetal lung maturation of antenatal betamethasone-acetate in preterm fetal sheep.Study designGroups of 10 singleton-pregnant ewes received 1 or 2 intramuscular doses 24 hours apart of 0.25 mg/kg/dose of betamethasone-phosphate+betamethasone-acetate (the standard of care dose) or 1 intramuscular dose of 0.5 mg/kg, 0.25 mg/kg, or 0.125 mg/kg of betamethasone-acetate. Fetuses were delivered 48 hours after the first injection at 122 days of gestation (80% of term) and ventilated for 30 minutes, with ventilator settings, compliance, vital signs, and blood gas measurements recorded every 10 minutes. After ventilation, we measured static lung pressure-volume curves and sampled the lungs for messenger RNA measurements. Other groups of pregnant ewes and fetuses were catheterized and treated with intramuscular injections of betamethasone-phosphate 0.125 mg/kg, betamethasone-acetate 0.125 mg/kg, or betamethasone-acetate 0.5 mg/kg. Maternal and fetal betamethasone concentrations in plasma were measured for 24 hours.ResultsAll betamethasone-treated groups had increased messenger RNA expression of surfactant proteins A, B, and C, ATP-binding cassette subfamily A member 3, and aquaporin-5 compared with control animals. Treatment with 1 dose of intramuscular betamethasone-acetate 0.125mg/kg improved dynamic and static lung compliance, gas exchange, and ventilation efficiency similarly to the standard treatment of 2Â doses of 0.25 m/kg of betamethasone-acetate+betamethasone-phosphate. Betamethasone-acetate 0.125 mg/kg resulted in lower maternal and fetal peak plasma concentrations and decreased fetal exposure to betamethasone compared with betamethasone-phosphate 0.125 mg/kg.ConclusionA single dose of betamethasone-acetate results in similar fetal lung maturation as the 2-dose clinical formulation of betamethasone-phosphate+betamethasone-acetate with decreased fetal exposure to betamethasone. A lower dose of betamethasone-acetate may be an effective alternative to induce fetal lung maturation with less risk to the fetus
Evaluation of food record charts used within the hospital setting to estimate energy and protein intakes
Britain has a serious shortage of nurses, as well as problems in recruiting and retaining them It is not simply that there are too few nurses; some key skills shortages also exist, with increasing demand for more qualified staff in some areas Much better planning of the workforce is required, and this needs to be more integrated with the planning for other groups in healthcare A change in the pay system may help, but the creation of better work environments may be part of the solution The rapid pace of change in the nursing profession has produced a challenge that the NHS needs to addresssch_die10pub4106pub1
Prevalence and Characteristics of Australians Complementary Medicine Product Use, and Concurrent Use with Prescription and Over-the-Counter Medications—A Cross Sectional Study
Data about the characteristics and prevalence of complementary medicine (CM) product use by Australians, including concurrent use with prescription and over-the-counter medications, have not been collected in the last five years. A cross-sectional online survey involving a representative sample of the Australian population was administered in 2021–2022. Of the 2351 survey responses included in this study, 49.4% reported use of a CM product over the previous 12-month period. Of these, 50% reported they always or often used CM products on the same day as a prescription medicine. Participants aged 65 and over were five times more likely to use CMs and other medications on the same day compared to 18–24-year-olds. Lower levels of education and having a chronic illness were also predictors of same-day use. The prevalence and characteristics of CM use by participants was similar to data collected five years ago. The study shows that concurrent use of CM products with prescription medications among older and more vulnerable populations is prevalent and this area requires further research to help ensure appropriate and safe use of CM products
