Article Synopsis
  • * The study compared the effects of term and preterm human milk EVs on immune-related cytokines and cell death, revealing that term EVs significantly inhibit pro-inflammatory cytokines like IL-6 and IL-1β, while both types reduce cell death related to inflammation.
  • * The findings suggest that the microRNA content in human milk EVs plays a key role in promoting immune tolerance and maintaining a balanced immune response, indicating potential therapeutic uses for EV supplementation in vulnerable newborns based on their

We investigated the associations between sociodemographic factors, religiosity traits, and the perception of discrimination among Muslim Americans in both everyday life and medical settings. A self-administered web-based questionnaire, comprising validated measures of discrimination and religiosity, was completed by a convenience sample of English-speaking adult Muslim Americans, recruited through both in-person and online channels. Among the 1281 respondents, less than half were born in the USA (46%), and a significant portion displayed visible religious markers, such as wearing a hijab or having a beard (61%).

Necrosome activation following TLR- or cytokine receptor-signaling results in cell death by necroptosis which is characterized by the rupture of cell membranes and the consequent release of intracellular contents to the extracellular milieu. While necroptosis exacerbates various inflammatory diseases, the mechanisms through which the inflammatory responses are regulated are not clear. We show that the necrosome activation of macrophages results in an upregulation of various pathways, including the mitogen-activated protein kinase (MAPK) cascade, which results in an elevation of the inflammatory response and consequent expression of several cytokines and chemokines.

Natural killer (NK) cells are predominant innate lymphocytes that initiate the early immune response during infection. NK cells undergo a metabolic switch to fuel augmented proliferation and activation following infection. Tumor necrosis factor-alpha (TNFα) is a well-known inflammatory cytokine that enhances NK cell function; however, the mechanism underlying NK cell proliferation in response to TNFα is not well established.

 Career satisfaction and burnout among physicians are important to study because they impact healthcare quality, outcomes, and physicians' well-being. Relationships between religiosity and these constructs are underexplored, and Muslim American physicians are an understudied population.  To explore relationships between career satisfaction, burnout, and callousness and Muslim physician characteristics, a questionnaire including measures of religiosity, career satisfaction, burnout, callousness, and sociodemographic characteristics was mailed to a random sample of Islamic Medical Association of North America members.
