A comprehensive study of the angular distributions in the bottom-baryon decays Λ_{b}^{0}→Λ_{c}^{+}h^{-}(h=π,K), followed by Λ_{c}^{+}→Λh^{+} with Λ→pπ^{-} or Λ_{c}^{+}→pK_{S}^{0} decays, is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 9 fb^{-1} collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The decay parameters and the associated charge-parity (CP) asymmetries are measured, with no significant CP violation observed. For the first time, the Λ_{b}^{0}→Λ_{c}^{+}h^{-} decay parameters are measured.

- The study investigates CP symmetry violation in the decay of D^{+} particles into K^{-}K^{+}π^{+} using data from proton-proton collisions at a high energy of 13 TeV.
- A unique model-independent method was employed to analyze the phase-space distributions of D^{+} and D^{-} particles, correcting for any instrumental biases using D_{s}^{+} decays.
- The findings indicate no significant evidence of CP violation, with a p value of 8.1%, and measure specific CP asymmetry observables, marking this study as the most sensitive search of its kind in multibody decays.
Maternity Care Informed Consent Practices and Perspectives: A Qualitative Study at a Tertiary Maternity Unit.
Aust N Z J Obstet Gynaecol
December 2024
Background: Although consent has long been accepted as necessary in maternity care, the concept of informed consent for planned vaginal birth has polarised maternity politics. The publication of the NSW Consent Manual outlines new standards of informed consent, signalling the need for examination of current maternity consent practices.
Aims: To examine informed consent and disclosure of material risks in birth in a prospective qualitative study of midwives and obstetricians.
Article Synopsis
- The study explores the impact of violence exposure on anxiety and psychiatric disorders in adolescents, particularly focusing on how perceived safety and threat sensitivity may mediate these effects.
- A sample of 54 adolescents completed an online survey, revealing that perceived safety is linked to lower anxiety and threat sensitivity, while violence exposure itself did not show a significant connection.
- The results suggest that increasing perceived safety could protect against anxiety, with threat sensitivity serving as a key factor in this relationship, indicating a potential avenue for intervention.
Background: The endocannabinoid system, which regulates fear- and anxiety-related behaviors, is dysregulated in adults with posttraumatic stress disorder (PTSD), as indicated by higher circulating anandamide (AEA) concentrations. The C385A (rs324420) polymorphism in the fatty acid amide hydrolase (FAAH) gene, which catabolizes AEA, is linked to higher AEA concentrations and greater PTSD symptoms in adults. Given that adolescence is a critical period during which trauma and psychiatric disorders emerge, understanding this relationship in youth is essential.
