Health-related quality of life after ileoanal pull-through evaluation and assessment of new health status measures

AbstractBACKGROUND & AIMS: Health-related quality of life (HRQL) after proctocolectomy is a critical parameter for management decisions in patients with chronic pancolitis. The aim of this study was to evaluate the HRQL of patients with ileoanal pull-through and to validate new, easy-to-administer HRQL measures. METHODS:The Sickness Impact Profile (SIP), Short Form 36 (SF-36), Rating Form of Inflammatory Bowel Disease (IBD) Patient Concerns (RFIPC), and the time trade-off (TTO) were used to measure HRQL of pull-through patients. The SF-36 and the RFIPC were validated. RESULTS: HRQL of patients with ileoanal pull-through was better than that of a national sample of patients with IBD (SIP and RFIPC) and similar to that of a normal population (SF-36). Physical and psychosocial subscales of the SF-36 correlated with the SIP, affirming the construct validity of the SF-36. The RFIPC results correlated with the SIP and SF-36 results, suggesting that it is also a valid health status measure for these patients. TTO results correlated with the physical subscales of the SIP and SF-36, reflecting the impact of physical health on this group. CONCLUSIONS: HRQL of patients with ileoanal pull-through is excellent. The SF-36 and RFIPC are valid health status measures that can be used by clinicians and researchers in these patients. (Gastroenterology 1997 Jul;113(1):7-14

Distinctive Left-Sided Distribution of Adrenergic-Derived Cells in the Adult Mouse Heart

Adrenaline and noradrenaline are produced within the heart from neuronal and non-neuronal sources. These adrenergic hormones have profound effects on cardiovascular development and function, yet relatively little information is available about the specific tissue distribution of adrenergic cells within the adult heart. The purpose of the present study was to define the anatomical localization of cells derived from an adrenergic lineage within the adult heart. To accomplish this, we performed genetic fate-mapping experiments where mice with the cre-recombinase (Cre) gene inserted into the phenylethanolamine-n-methyltransferase (Pnmt) locus were cross-mated with homozygous Rosa26 reporter (R26R) mice. Because Pnmt serves as a marker gene for adrenergic cells, offspring from these matings express the β-galactosidase (βGAL) reporter gene in cells of an adrenergic lineage. βGAL expression was found throughout the adult mouse heart, but was predominantly (89%) located in the left atrium (LA) and ventricle (LV) (p<0.001 compared to RA and RV), where many of these cells appeared to have cardiomyocyte-like morphological and structural characteristics. The staining pattern in the LA was diffuse, but the LV free wall displayed intermittent non-random staining that extended from the apex to the base of the heart, including heavy staining of the anterior papillary muscle along its perimeter. Three-dimensional computer-aided reconstruction of XGAL+ staining revealed distribution throughout the LA and LV, with specific finger-like projections apparent near the mid and apical regions of the LV free wall. These data indicate that adrenergic-derived cells display distinctive left-sided distribution patterns in the adult mouse heart

Long-Term Surgical Recurrence, Morbidity, Quality of Life, and Body Image of Laparoscopic-Assisted vs. Open Ileocolic Resection for Crohn’s Disease: A Comparative Study

PurposeSeveral studies have compared conventional open ileocolic resection with a laparoscopic-assisted approach. However, long-term outcome after laparoscopic-assisted ileocolic resection remains to be determined. This study was designed to compare long-term results of surgical recurrence, quality of life, body image, and cosmesis in patients who underwent laparoscopic-assisted or open ileocolic resection for Crohn's disease.MethodsSeventy-eight consecutive patients who underwent ileocolic resection during the period 1995 to 1998 were analyzed; 48 underwent a conventional open approach in the Academic Medical Centre (Amsterdam, The Netherlands) and 30 underwent a laparoscopic-assisted approach in the Leiden University Medical Centre (Leiden, The Netherlands). Primary outcome parameters were reoperation and readmission rate. Secondary outcome parameters were quality of life, body image, and cosmesis.ResultsThe two groups were comparable for characteristics of sex, age, and immunosuppressive therapy. Seventy-one patients had a complete follow-up of median 8.5 years. Resection for recurrent Crohn's disease was performed in 6 of 27 (22 percent) and 10 of 44 (23 percent) patients in the laparoscopic and open groups, respectively. Reoperations for incisional hernia were only performed after conventional open ileocolic resection (3/44 = 6.8 percent). Quality of life and body image were comparable, but cosmesis scores were significantly higher in the laparoscopic group.ConclusionsDespite small numbers, we found that surgical recurrence and quality of life after laparoscopic-assisted and open ileocolic resection were comparable. Incisional hernias occurred only after open ileocolic resection, and laparoscopic-assisted ileocolic resection resulted in a significantly better cosmesis

EQ-5D in Central and Eastern Europe : 2000-2015

Objective: Cost per quality-adjusted life year data are required for reimbursement decisions in many Central and Eastern European (CEE) countries. EQ-5D is by far the most commonly used instrument to generate utility values in CEE. This study aims to systematically review the literature on EQ-5D from eight CEE countries. Methods: An electronic database search was performed up to July 1, 2015 to identify original EQ-5D studies from the countries of interest. We analysed the use of EQ-5D with respect to clinical areas, methodological rigor, population norms and value sets. Results: We identified 143 studies providing 152 country-specific results with a total sample size of 81,619: Austria (n=11), Bulgaria (n=6), Czech Republic (n=18), Hungary (n=47), Poland (n=51), Romania (n=2), Slovakia (n=3) and Slovenia (n=14). Cardiovascular (20%), neurologic (16%), musculoskeletal (15%) and endocrine/nutritional/metabolic diseases (14%) were the most frequently studied clinical areas. Overall 112 (78%) of the studies reported EQ VAS results and 86 (60%) EQ-5D index scores, of which 27 (31%) did not specify the applied tariff. Hungary, Poland and Slovenia have population norms. Poland and Slovenia also have a national value set. Conclusions: Increasing use of EQ-5D is observed throughout CEE. The spread of health technology assessment activities in countries seems to be reflected in the number of EQ-5D studies. However, improvement in informed use and methodological quality of reporting is needed. In jurisdictions where no national value set is available, in order to ensure comparability we recommend to apply the most frequently used UK tariff. Regional collaboration between CEE countries should be strengthened

A systems approach identifies co-signaling molecules of early growth response 1 transcription factor in immobilization stress

Adaptation to stress is critical for survival. The adrenal medulla, the major source of epinephrine, plays an important role in the development of the hyperadenergic state and increased risk for stress associated disorders, such as hypertension and myocardial infarction. The transcription factor Egr1 plays a central role in acute and repeated stress, however the complexity of the response suggests that other transcription factor pathways might be playing equally important roles during acute and repeated stress. Therefore, we sought to discover such factors by applying a systems approach. Using microarrays and network analysis we show here for the first time that the transcription factor signal transducer and activator of transcription 3 (Stat3) gene is activated in acute stress whereas the prolactin releasing hormone (Prlh11) and chromogranin B (Chgb) genes are induced in repeated immobilization stress and that along with Egr1 may be critical mediators of the stress response. Our results suggest possible involvement of Stat3 and Prlh1/Chgb up-regulation in the transition from short to repeated stress activation

l-N-acetylcysteine protects outer hair cells against TNFα initiated ototoxicity in vitro

Objective: The present study is aimed at determining the efficacy and exploring the mechanisms by which l-N-acetylcysteine (l-NAC) provides protection against tumor necrosis factor-alpha (TNFα)-induced oxidative stress damage and hair cell loss in 3-day-old rat organ of Corti (OC) explants. Previous work has demonstrated a high level of oxidative stress in TNFα-challenged OC explants. TNFα can potentially play a significant role in hair cell loss following an insult to the inner ear. l-NAC has shown to provide effective protection against noise-induced hearing loss in laboratory animals but mechanisms of this otoprotective effect are not well-defined. Design: Rat OC explants were exposed to either: (1) saline control (N = 12); (2) TNFα (2 μg/ml, N = 12); (3) TNFα+l-NAC (5 mM, N = 12); (4) TNFα+l-NAC (10 mM, N = 12); or (5) l-NAC (10 mM, N = 12). Outer hair cell (OHC) density, levels of reactive oxygen species (ROS), lipid peroxidation of cell membranes, gluthathione activity, and mitochondrial viability were assayed. Results: l-NAC (5 and 10 mM) provided protection for OHCs from ototoxic level of TNFα in OC explants. Groups treated with TNFα+l-NAC (5 mM) showed a highly significant reduction of both ROS (p < 0.01) and 4-hydroxy-2-nonenal immunostaining (p < 0.001) compared to TNFα-challenged explants. Total glutathione levels were low in TNFα-challenged explants compared to control and TNFα+l-NAC (5 mM) treated explants (p < 0.001). Conclusions: l-NAC is a promising treatment for protecting auditory HCs from TNFα-induced oxidative stress and subsequent loss via programmed cell death
