Background: Dying in childbirth is one of the most common causes of death for women. While maternal mortality rates, defined as deaths per 100,000 live births, have been steadily dropping in most countries worldwide, maternal mortality rates have doubled in the United States in the last twenty years. This commentary examines the various contributing factors to this trend. Methods: A literature review was performed using the keywords: maternal mortality, United States, disrespectful maternity care, obstetric violence, provider perspectives, and disparities. Maternal mortality statistics were obtained from the World Health organization website. Results: Medical factors associated with maternal mortality include increased maternal age and cardiovascular conditions. Social factors include barriers to healthcare access, delays in receiving medical care, reduction in reproductive health services in some states, and non-obstetrical deaths such as accidents, domestic violence, and suicide. Racial inequities and disparities of care are reflected in higher maternal mortality rates for minorities and people of color. Disrespectful maternity care or obstetric violence has been reported worldwide as a factor in delay of lifesaving obstetrical care and reluctance by a pregnant person to access the healthcare system. About one in five US women has reported experiencing mistreatment, varying from verbal abuse to lack of privacy, from coerced procedures to neglect during childbirth. Conclusion: This commentary highlights the importance of inclusion of providers in research on respectful maternity care. Provider burnout, moral distress, limited time, and burden of clinical responsibilities are known challenges to respectful and comprehensive medical care. The association of disrespectful care with poor maternal outcomes needs to be studied. Exploring root causes of disrespectful childbirth care can empower nurses, midwives, and physicians to improve their environment and find solutio

Background The timing of behavior and habitat use of nocturnal animals can be influenced by the lunar cycle in nature. The prevalence of artificial light at night(ALAN) has been recognized as a source of environmental pol-lution. The interaction between ALAN and the lunar cycle on bat behavior is important for understanding anthro-pogenic effects on bats. We utilized a decade(2012–2022) of acoustic monitoring data collected in North Carolina, United States, to investigate the relationship between bat activity, lunar cycle, and light pollution. We examined whether the amount of lunar illumination affected species-specific nightly activity and whether hourly bat activity patterns varied between nights with different moon phases. We further investigated if the relationship between bat activity and the lunar cycle might be altered by light *** We found that seven bat species showed activity variation across nights in relation to the amount of moon illumination when ALAN was absent. In general, bats were less active on full moon nights compared to new moon nights. Light pollution interacted with the bat–lunar relationship in five of the seven species, masking the effect of the lunar cycle. We identified delayed bat activity patterns on nights with a full or waxing moon in seven species, and light pollution altered that pattern in four species. overall, ALAN was associated with decreased bat activity inde-pendent of lunar cycle *** our study demonstrated that at a broad spatial scale, ALAN negatively affected many North American temperate bat species and altered their lunar chronobiology. As light pollution is spreading to historically dark areas and habitats, ALAN might couple with other threats, such as the white-nose syndrome or climate change, to cause cascading damage in the environment that depends on ecosystem services such as pest control provided by bats. We argue that further research and conservation actions are needed to mitigate
