Intestinal Pseudo-Obstruction Complicating Multiple Sclerosis

Three patients with intestinal pseudo-obstruction secondary to multiple sclerosis are reported. This is a serious complication with significant morbidity and mortality, which is infrequently recognized in clinical practice and rarely reported in the medical literature

The Correlation Between Transformational Leadership and Mental Health Clinician Burnout

Mental health clinicians working in a hospital setting are at a high risk of experiencing burnout due to the stressful demands of their caseloads, compassion fatigue, limited resources, and unsupportive leadership. While there is ample research regarding the cause and effect of burnout on clinicians there is a gap in the literature when it comes to the impact leadership has on mental heath clinician burnout. The purpose of this quantitative, correlational study is to determine if and to what extent there is a correlation between Transformational Leadership and mental health clinician burnout. Participants for this study consisted of 200 mental health clinicians working in inpatient mental health hospitals. Each clinician was sent a link for the anonymous, electronic survey with questions from the Leadership Behavior Inventory, to assess their perception of their direct supervisor’s level of Transformational Leadership Qualities, and the Copenhagen Burnout Inventory to assess their level of personal, work-related, and client-related burnout. Of the 200 surveys sent out, 112 were completed fully and returned. The data was analyzed using Spearman’s Rho Correlational test with the independent variable being Transformational Leadership, and the dependent variables of personal burnout, work-related burnout, and client-related burnout. The study findings were significant, suggesting that there is a negative correlation between Transformational Leadership and the three dimensions of clinician burnout. These research findings may be helpful for mental health hospital administrators to develop a leadership training for their clinical supervisors to adopt a Transformational Leadership style that can help mitigate burnout in their clinicians. Keywords: mental health clinician, burnout, transformational leadershi

Menstrual Cycle Effects on Blood Pressure, Body Weight and Heart Rates During Rest, Exercise and Recovery on College Athletes

Ten members of the Eastern Illinois University women\u27s track team were used as subjects to determine the relationship of body weight, blood pressure and heart rate during rest, exercise and recovery to menstruation. The subjects were tested on two different occasions. The first test was administered within twenty-four hours of the onset of menstruation. The second test was conducted seven days later. During both testing periods blood pressure, body weight and resting heart rate measurements were taken before beginning the treadmill protocol (progressive grade and speed increases up to 4% and 8 mph, respectively). The subjects ran on a motor driven treadmill for five minutes while their heart rates were being monitored every minute. Within two minutes of the completion of the treadmill protocol, a seated recovery blood pressure measurement was taken. Recovery heart rates were also monitored every minute for five minutes. The BMDP2V- analysis of variance program, including repeated measures, was used to determine whether there was any difference between each minute of exercise and recovery between the two tests. A t-test was used to determine the differences between mean blood pressures taken before and after exercise as well as body weight and heart rates for both test days. The study revealed that menstruation had no significant effect on blood pressure, body weight or heart rate responses at rest, during exercise or in recovery from exercise

DLL4 promotes continuous adult intestinal lacteal regeneration and dietary fat transport.

The small intestine is a dynamic and complex organ that is characterized by constant epithelium turnover and crosstalk among various cell types and the microbiota. Lymphatic capillaries of the small intestine, called lacteals, play key roles in dietary fat absorption and the gut immune response; however, little is known about the molecular regulation of lacteal function. Here, we performed a high-resolution analysis of the small intestinal stroma and determined that lacteals reside in a permanent regenerative, proliferative state that is distinct from embryonic lymphangiogenesis or quiescent lymphatic vessels observed in other tissues. We further demonstrated that this continuous regeneration process is mediated by Notch signaling and that the expression of the Notch ligand delta-like 4 (DLL4) in lacteals requires activation of VEGFR3 and VEGFR2. Moreover, genetic inactivation of Dll4 in lymphatic endothelial cells led to lacteal regression and impaired dietary fat uptake. We propose that such a slow lymphatic regeneration mode is necessary to match a unique need of intestinal lymphatic vessels for both continuous maintenance, due to the constant exposure to dietary fat and mechanical strain, and efficient uptake of fat and immune cells. Our work reveals how lymphatic vessel responses are shaped by tissue specialization and uncover a role for continuous DLL4 signaling in the function of adult lymphatic vasculature

Common Data Elements for Disorders of Consciousness: Recommendations from the Working Group on Outcomes and Endpoints

BackgroundClinical management of persons with disorders of consciousness (DoC) is dedicated largely to optimizing recovery. However, selecting a measure to evaluate the extent of recovery is challenging because few measures are designed to precisely assess the full range of potential outcomes, from prolonged DoC to return of preinjury functioning. Measures that are designed specifically to assess persons with DoC are often performance-based and only validated for in-person use. Moreover, there are no published recommendations addressing which outcome measures should be used to evaluate DoC recovery. The resulting inconsistency in the measures selected by individual investigators to assess outcome prevents comparison of results across DoC studies. The National Institute of Neurological Disorders and Stroke (NINDS) common data elements (CDEs) is an amalgamation of standardized variables and tools that are recommended for use in studies of neurologic diseases and injuries. The Neurocritical Care Society Curing Coma Campaign launched an initiative to develop CDEs specifically for DoC and invited our group to recommend CDE outcomes and endpoints for persons with DoCs.MethodsThe Curing Coma Campaign Outcomes and Endpoints CDE Workgroup, consisting of experts in adult and pediatric neurocritical care, neurology, and neuroscience, used a previously established five-step process to identify and select candidate CDEs: (1) review of existing NINDS CDEs, (2) nomination and systematic vetting of new CDEs, (3) CDE classification, (4) iterative review and approval of panel recommendations, and (5) development of case report forms.ResultsAmong hundreds of existing NINDS outcome and endpoint CDE measures, we identified 20 for adults and 18 for children that can be used to assess the full range of recovery from coma. We also proposed 14 new outcome and endpoint CDE measures for adults and 5 for children.ConclusionsThe DoC outcome and endpoint CDEs are a starting point in the broader effort to standardize outcome evaluation of persons with DoC. The ultimate goal is to harmonize DoC studies and allow for more precise assessment of outcomes after severe brain injury or illness. An iterative approach is required to modify and adjust these outcome and endpoint CDEs as new evidence emerges

A trial of intracranial pressure monitoring in traumatic brain injury

Background Intracranial pressure (ICP) monitoring is considered the standard of care for severe traumatic brain injury (TBI) and is used frequently, but the efficacy of treatment based on monitoring in improving the outcome has not been rigorously assessed. Methods Objective: The objective was to compare efficacy of guideline-based management in which a protocol for monitoring intraparenchymal ICP was used (ICP group) or a protocol in which treatment was based on imaging and clinical examination (exam group). Design: A multicenter randomized controlled trial was conducted. Setting: The trial was set in ICUs in Bolivia or Ecuador. Subjects: Patients had severe TBI (n = 324) and were 13 years of age or older. Interventions: Patients were randomly allocated to ICP This composite measure was based on performance across 21 measures of functional and cognitive status and was calculated as a percentile (with 0 indicating the worst performance, and 100 the best performance). Results There was no significant between-group difference in the primary outcome, a composite measure based on percentile performance across 21 measures of functional and cognitive status (score 56 in the pressure-monitoring group versus 53 in the imaging-clinical examination group; P= 0.49). Six-month mortality rates were 39% in the pressuremonitoring group and 41% in the imaging-clinical examination group (P = 0.60). The median lengths of stay in the ICU were similar in the two groups (12 days in the pressure-monitoring group and 9 days in the imagingclinical examination group; P = 0.25), although the number of days of brain-specific treatments (for example, administration of hyperosmolar fluids and the use of hyperventilation) in the ICU was higher in the imaging-clinical examination group than in the pressure-monitoring group (4.8 versus 3.4, P = 0.002). The distributions of serious adverse events were similar in the two groups. Conclusions For patients with severe TBI, care focused on maintaining monitored ICP at 20 mmHg or less was not shown to be superior to care based on imaging and clinical examination. monitoring or clinical exam-based monitoring. Outcomes: The primary outcome was a composite of survival time, impaired consciousness, functional status at 3 and 6 months, and neuropsychological status at 6 months; neuropsychological status was assessed by an examiner who was unaware of the protocol assignment. © 2014 BioMed Central Ltd

Melanocortin receptor accessory proteins in adrenal disease and obesity.

Melanocortin receptor accessory proteins (MRAPs) are regulators of the melanocortin receptor family. MRAP is an essential accessory factor for the functional expression of the MC2R/ACTH receptor. The importance of MRAP in adrenal gland physiology is demonstrated by the clinical condition familial glucocorticoid deficiency type 2. The role of its paralog melanocortin-2-receptor accessory protein 2 (MRAP2), which is predominantly expressed in the hypothalamus including the paraventricular nucleus, has recently been linked to mammalian obesity. Whole body deletion and targeted brain specific deletion of the Mrap2 gene result in severe obesity in mice. Interestingly, Mrap2 complete knockout (KO) mice have increased body weight without detectable changes to food intake or energy expenditure. Rare heterozygous variants of MRAP2 have been found in humans with severe, early-onset obesity. In vitro data have shown that Mrap2 interaction with the melanocortin-4-receptor (Mc4r) affects receptor signaling. However, the mechanism by which Mrap2 regulates body weight in vivo is not fully understood and differences between the phenotypes of Mrap2 and Mc4r KO mice may point toward Mc4r independent mechanisms
