Article Synopsis
  • Surface sterilization of fertile eggs with 70% ethanol is commonly used in broiler breeding to prevent infections, but it can also eliminate beneficial microbes that aid embryo development.
  • A study was conducted with 460 Ross 308 fertile eggs divided into sterilized and unsterilized groups to assess the effects of this sterilization on the yolk microbiota and embryo growth.
  • Results indicated that while sterilization improved embryo development from E15 to E21, it also decreased the diversity of the yolk microbiota, resulting in lower levels of beneficial bacteria but fewer pathogens.

Introduction: Nasal packing is commonly employed in the emergency department (ED) to manage epistaxis that does not respond to conservative treatments. However, this intervention may increase the risk of nasal septal perforation (NSP) due to reduced blood flow to the nasal septum. No prior study has explored the relationship between nasal packing and risk of NSP.

The assumption of "no unmeasured confounders" is a critical but unverifiable assumption required for causal inference yet quantitative sensitivity analyses to assess robustness of real-world evidence remains under-utilized. The lack of use is likely in part due to complexity of implementation and often specific and restrictive data requirements for application of each method. With the advent of methods that are broadly applicable in that they do not require identification of a specific unmeasured confounder-along with publicly available code for implementation-roadblocks toward broader use of sensitivity analyses are decreasing.

  • A study involving 2860 mother-child pairs examined how prenatal exposure to certain antibiotics, specifically Tetracycline and Ofloxacin, may influence the development of autism spectrum disorder (ASD) symptoms in children by analyzing urinary concentrations during pregnancy.
  • The research found that maternal exposure to Tetracycline throughout pregnancy significantly elevated the risk of ASD symptoms, particularly during the first and third trimesters in boys, while Ofloxacin exposure during the first trimester posed increased risk for girls.
  • No clear dose-dependent relationship was established, indicating that it was the presence of these antibiotics during specific pregnancy periods that correlated with heightened ASD symptoms rather than the amount of exposure.
