Given the increasing integration of trusted leaders in public health science, including vaccination programs, context-specific understandings of community perceptions and levels of trust are critical to intervention. This study aimed to understand the perspectives and attitudes of the southeastern Louisiana community and inform the development of a community-engaged action plan. A cross-sectional survey of 555 southeastern Louisianans-including faith-based organization (FBO) members, community pharmacy (CommRx) customers, community-based organization (CBO) contacts, and Louisiana community-dwelling residents-was conducted from November 2020 to March 2021.

Children with neurodegenerative disease often have debilitating gastrointestinal symptoms. We hypothesized that this may be due at least in part to underappreciated degeneration of neurons in the enteric nervous system (ENS), the master regulator of bowel function. To test this hypothesis, we evaluated mouse models of neuronal ceroid lipofuscinosis type 1 and 2 (CLN1 and CLN2 disease, respectively), neurodegenerative lysosomal storage disorders caused by deficiencies in palmitoyl protein thioesterase-1 and tripeptidyl peptidase-1, respectively.

After years of armed conflict in northern Uganda, many local people have turned to Evangelical churches for help with healing and recovery. We observe that the healing practices in these churches encourage particular notions of what the mind is, how the mind works and whether it is bounded or porous to the outside world. In the traditional cultural setting in which these people grew to adulthood, many accept that vengeance can attack supernaturally from without.

Article Synopsis
  • Pseudomonas aeruginosa, when losing DNA mismatch repair (MMR), becomes a hypermutator, leading to high rates of multidrug resistance (MDR), especially after exposure to antibiotics.
  • Hypermutated MMR-deficient P. aeruginosa has a specific mutational signature and quickly develops MDR through shared resistance mechanisms across different drug classes.
  • Analyzing mutational signatures of P. aeruginosa in patients shows many MMR-deficient strains are already MDR or likely to become resistant, indicating that this analysis could be a valuable diagnostic tool for predicting and managing MDR in clinical settings.

Runners often reduce their pace during inclined running to maintain a constant metabolic workload, known as iso-efficiency speed (a speed-incline combination with the same metabolic intensity as level running). This study investigates changes in lower extremity (LE) joint work profiles when running on an incline at iso-efficiency speed. Eleven collegiate distance runners completed a treadmill running task under three conditions (0%, 4%, and 8% incline).

The gut microbiome plays a key role in the pathogenesis and disease activity of inflammatory bowel disease (IBD). While research has focused on the bacterial microbiome, recent studies have shifted towards host genetics and host-fungal interactions. The mycobiota is a vital component of the gastrointestinal microbial community and plays a significant role in immune regulation.

Black women bear a disproportionately higher burden of cervical cancer than any ethnic/racial group. Patient's cancer risk perceptions and patient-provider communication behavior may influence uptake of cervical cancer screening with Papanicolaou (Pap) test. We examined the association of cancer risk perceptions and patient-provider communication behavior and Pap test uptake.

Emotion regulation (ER), or the ability to modulate the experience and expression of emotion, is critical to adaptive functioning and is a key feature of mood disorders. At the same time, normal aging is associated with changes in ER, though the interaction of aging with the presence of a mood disorder are unclear. Here, we review what is known about ER and its underlying neural mechanisms in late life mood disorders, specifically late life depression and bipolar disorder.

The use of normothermic machine perfusion (NMP) over static cold storage in liver transplantation has been shown to reduce posttransplant risks of early allograft dysfunction, primary nonfunction, and ischemic cholangiopathy, and its increasing use has played a role in the expanded utilization of marginal livers. While studies have demonstrated improved clinical outcomes using NMP over static cold storage preservation, real-time intraoperative data reflecting the quality and viability of NMP livers is limited. This retrospective, single-center study compared NMP versus static cold storage livers in first-time recipients of liver transplants through the evaluation of synthetic coagulation function as measured by thromboelastography and conventional coagulation testing.
