RESUMEN

BACKGROUND: Ulcerative Colitis (UC) is a chronic, inflammatory disease, characterized by symptomatic periods (flare) interspersed with asymptomatic periods (remission). Evidence suggests that psychological stress can trigger flare. Studies have shown that mindfulness interventions (MI) reduce stress, foster more adaptive coping, and improve quality of life, but have been minimally used for UC patients. The objective of this study was to determine whether participation in an MI results in improvements in UC disease course and inflammatory cascades, mindfulness, perceived stress, and other psychological outcomes in inactive UC patients with limited or no exposure to past MI. METHODS: Participants were randomized to an 8-week MI or control group. Biological and psychological assessments were performed at baseline, post 8-week course, and at 6- and 12-months. RESULTS: Forty-three participants enrolled. The MI increased the state of mindfulness and mindfulness skills, decreased perceived stress and stress response in patients with inactive UC. The MI intervention significantly decreased the incidence of flare over 12 months (P < .05). None of the UC patients in the MI flared during 12 months, while 5 of 23 (22%) control group participants flared during the same period. CONCLUSIONS: MIs could be considered as adjuvant treatment for a subset of UC patients with high perceived stress and low state of mindfulness.The trial was registered at clinicaltrials.gov as NCT01491997.


Inactive ulcerative colitis patients were randomized to a mindfulness intervention or control group. Biological and psychological assessments were performed over 12 months. The intervention significantly decreased the incidence of flares, increased the state of mindfulness and mindfulness skills, and decreased perceived stress and the stress response.

RESUMEN

BACKGROUND: The shortage of nursing faculty is well documented as are the challenges of attracting and retaining early-career faculty, in part, due to difficulties transitioning expert clinicians into faculty roles. PROBLEM: There is little guidance in the literature describing successful formal transition models. APPROACH: An urban College of Nursing Faculty Practice (CON FP) underwent an operational redesign beginning in 2014, resulting in an intentional success: a pipeline for attracting and developing early-career faculty. This article describes how the CON FP leverages faculty practice to develop early-career faculty. OUTCOMES: Across a 6-year time span, at least 20 early-career CON FP clinicians have transitioned to full-time faculty roles. In addition, CON FP clinicians provide more than 75 000 direct care nursing services and support more than 25 000 student clinical and project hours annually. CONCLUSIONS: We offer this early-career faculty practice pipeline model as a solution for attracting and growing a contemporary nursing faculty workforce.

RESUMEN

Microbiota derived short chain fatty acids (SCFAs) are produced by fermentation of nondigestible fiber, and are a key component in intestinal barrier homeostasis. Since the microbiome has diurnal fluctuations, we hypothesized that SCFAs in humans have a diurnal rhythm and their rhythmicity would be impacted by the host central circadian misalignment (night shift work) which would make intestinal barrier more susceptible to disruption by alcohol. To test this hypothesis, we studied 3 groups of subjects: patients with alcohol use disorder, but no liver disease (AD), healthy day workers (DW), and night workers (NW). All subjects were studied at baseline and then in DW and NW subjects after moderate daily alcohol (0.5 g/kg) for 7 days. Gut-derived plasma SCFAs showed a significant circadian oscillation by cosinor analysis in DW; however, SCFA in the AD and NW subjects lost 24-hour rhythmicity. Decrease in SCFA correlated with increased colonic permeability. Both chronic and moderate alcohol consumption for 1 week caused circadian disruption based on wrist actigraphy and urinary melatonin. Our study shows that (1) gut-derived plasma SCFAs have a diurnal rhythm in humans that is impacted by the central clock of the host; (2) moderate alcohol suppresses SCFAs which was associated with increased colonic permeability; and (3) less invasive urinary 6-SM correlated and rest-activity actigraphy correlated with plasma melatonin. Future studies are needed to examine the role circadian misalignment on gut derived SCFAs as possible mechanism for loss of intestinal barrier resiliency to injurious agents like alcohol.

RESUMEN

PURPOSE: Treatment of ulcerative colitis (UC), given its chronicity and its associated disruptive and often distressing symptoms, is increasingly focusing on maximizing patient quality of life. Poorer quality of life has been found among patients with poor sleep quality, which is much more common in patients with UC than in the general population and may be associated with inflammation and psychological distress. METHOD: Forty-seven patients with UC (n = 11 flaring) completed measures of sleep quality, depression, state anxiety, gastrointestinal-related anxiety, perceived stress, and quality of life. Measures of inflammation were also obtained. RESULTS: Patients endorsed high rates of poor sleep quality, which was highly correlated with depression and poorer inflammatory bowel disease-related quality of life, but was generally not related to other areas of psychological functioning or inflammation. Sleep quality was significantly independently associated with depression and female gender. CONCLUSION: Poor sleep quality is prevalent in patients with UC and is strongly related to depression, suggesting that sleep and mood are important areas to assess in patients with UC in order to inform tailored treatment to improve quality of life.

RESUMEN

Alcohol-induced intestinal hyperpermeability (AIHP) is a known risk factor for alcoholic liver disease (ALD), but only 20-30% of heavy alcoholics develop AIHP and ALD. The hypothesis of this study is that circadian misalignment would promote AIHP. We studied two groups of healthy subjects on a stable work schedule for 3 mo [day workers (DW) and night workers (NW)]. Subjects underwent two circadian phase assessments with sugar challenge to access intestinal permeability between which they drank 0.5 g/kg alcohol daily for 7 days. Sleep architecture by actigraphy did not differ at baseline or after alcohol between either group. After alcohol, the dim light melatonin onset (DLMO) in the DW group did not change significantly, but in the NW group there was a significant 2-h phase delay. Both the NW and DW groups had no change in small bowel permeability with alcohol, but only in the NW group was there an increase in colonic and whole gut permeability. A lower area under the curve of melatonin inversely correlated with increased colonic permeability. Alcohol also altered peripheral clock gene amplitude of peripheral blood mononuclear cells in CLOCK, BMAL, PER1, CRY1, and CRY2 in both groups, and inflammatory markers lipopolysaccharide-binding protein, LPS, and IL-6 had an elevated mesor at baseline in NW vs. DW and became arrhythmic with alcohol consumption. Together, our data suggest that central circadian misalignment is a previously unappreciated risk factor for AIHP and that night workers may be at increased risk for developing liver injury with alcohol consumption.

RESUMEN

Chronic heavy alcohol use is known to cause gut leakiness and alcoholic liver disease (ALD), but only 30% of heavy drinkers develop increased intestinal permeability and ALD. The hypothesis of this study was that disruption of circadian rhythms is a potential risk factor in actively drinking alcoholics for gut leakiness and endotoxemia. We studied 20 subjects with alcohol use disorder (AD) and 17 healthy controls (HC, 6 day workers, 11 night workers). Subjects wore a wrist actiwatch for 7 days and underwent a 24-h dim light phase assessment and urine collection for intestinal permeability. The AD group had significantly less total sleep time and increased fragmentation of sleep (P < 0.05). AD also had significantly lower plasma melatonin levels compared with the HC [mean area under the curve (AUC) 322.78 ± 228.21 vs. 568.75 ± 304.26 pg/ml, P = 0.03]. In the AD group, AUC of melatonin was inversely correlated with small bowel and colonic intestinal permeability (lactulose-to-mannitol ratio, r = -0.39, P = 0.03; urinary sucralose, r = -0.47, P = 0.01). Cosinor analysis of lipopolysaccharide-binding protein (marker of endotoxemia) and lipopolysaccharide every 4 h for 24 h in HC and AD subjects had a midline estimating statistic of rhythm of 5,026.15 ± 409.56 vs. 6,818.02 ± 628.78 ng/ml (P < 0.01) and 0.09 ± 0.03 vs. 0.15 ± 0.19 EU/ml (P < 0.05), respectively. We found plasma melatonin was significantly lower in the AD group, and lower melatonin levels correlated with increased intestinal permeability and a marker of endotoxemia. Our study suggests the suppression of melatonin in AD may promote gut leakiness and endotoxemia.

RESUMEN

HIV progression is characterized by immune activation and microbial translocation. One factor that may be contributing to HIV progression could be a dysbiotic microbiome. We therefore hypothesized that the GI mucosal microbiome is altered in HIV patients and this alteration correlates with immune activation in HIV. 121 specimens were collected from 21 HIV positive and 22 control human subjects during colonoscopy. The composition of the lower gastrointestinal tract mucosal and luminal bacterial microbiome was characterized using 16S rDNA pyrosequencing and was correlated to clinical parameters as well as immune activation and circulating bacterial products in HIV patients on ART. The composition of the HIV microbiome was significantly different than that of controls; it was less diverse in the right colon and terminal ileum, and was characterized by loss of bacterial taxa that are typically considered commensals. In HIV samples, there was a gain of some pathogenic bacterial taxa. This is the first report characterizing the terminal ileal and colonic mucosal microbiome in HIV patients with next generation sequencing. Limitations include use of HIV-infected subjects on HAART therapy.
