Separating Infectious Proctitis from Inflammatory Bowel Disease-A Common Clinical Conundrum.

Proctitis refers to inflammation in the rectum and may result in rectal bleeding, discharge, urgency, tenesmus, and lower abdominal pain. It is a common presentation, particularly in genitourinary medicine and gastroenterology, as the two most common causes are sexually transmitted infections and inflammatory bowel disease. The incidence of infective proctitis is rising, particularly amongst high-risk groups, including men who have sex with men, those with HIV seropositive status, and those participating in high-risk sexual behaviours.

The multi-dimensional stigma of chronic pain: A narrative review.

Accumulating evidence suggests that stigma is a pervasive and pernicious psychosocial phenomenon that affects people living with chronic pain. In this narrative review, we describe the nature of stigma experienced by people with chronic pain and discuss its multifaceted determinants. These determinants include features of pain itself and intersectional factors, including comorbid conditions and social marginalization.

Mental health and well-being in adolescent and young adult refugees in Sweden: A cross-sectional study of accompanied and unaccompanied individuals.

Background: Currently, approximately 100 million people are displaced worldwide, including children and young adults. Previous studies showed exposure to violence and posttraumatic stress disorder (PTSD) are common in this sub-population. However, we still lack comprehensive data on well-being, mental health, and the ability to function.

Uterotonics update.

Uterotonics are the mainstay of management for postpartum haemorrhage and an understanding of their use is essential for the obstetric anaesthetist. First-line uterotonics comprise oxytocin and carbetocin, which act on the oxytocin receptor, and recent research has shown that lower doses of first-line uterotonics can be used to adequate effect. The oxytocin receptor is known to undergo desensitisation with exposure to the agonist over time and with increasing concentrations.

Attitudes towards mental health professionals in social media: infodemiology study.

Background: Negative perceptions of mental health professionals can deter individuals from seeking mental healthcare. Given the high burden of mental health globally, it is essential to understand attitudes towards mental health professionals. Social media platforms like Twitter/X provide valuable insights into the views of the general population.

Capture, mutual inhibition and release mechanism for aPKC-Par6 and its multisite polarity substrate Lgl.

The mutually antagonistic relationship of atypical protein kinase C (aPKC) and partitioning-defective protein 6 (Par6) with the substrate lethal (2) giant larvae (Lgl) is essential for regulating polarity across many cell types. Although aPKC-Par6 phosphorylates Lgl at three serine sites to exclude it from the apical domain, aPKC-Par6 and Lgl paradoxically form a stable kinase-substrate complex, with conflicting roles proposed for Par6. We report the structure of human aPKCι-Par6α bound to full-length Llgl1, captured through an aPKCι docking site and a Par6 contact.
