Introduction: The association of gender with health status (HS) response to long-term oxygen therapy (LTOT) in very severe COPD is unclear. The aims of this study were: (1) to compare dyspnea perception and HS between male and female with very severe COPD at baseline and (2) to provide a prospective assessment of HS response to LTOT, according to gender.Patients and methods: Hypoxemic COPD (n =97, age: 65.5 +/- 9.6 years, 53% males) were enrolled in a prospective longitudinal study over 12 months or until death. St. George's Respiratory Questionnaire (SGRQ) and baseline dyspnea index (BDI) were assessed.Results: At baseline, HS impairment and dyspnea sensation were similar between genders. After 12 months of LTOT, women presented improvement in symptom (64.1 +/- 120.6 versus 40.6 +/- 122.9; P < 0.0001) and total SGRQ scores. Men also showed improvement in symptoms after 12 months (62.7 +/- 23.3 versus 49.6 +/- 22.8; P < 0.0005); however, they presented deterioration of activity, impact and total scores during the study period, with markedly decline of activity domain (68.5 +/- 20.0 versus 75.9 +/- 16.9; P = 0.008). BDI did not show significant difference by gender over the study period.Conclusions: Our results show that the HS course in very severe COPD patients differs according to gender, as females show greater response longitudinally to LTOT.

Little evidence-based guidance is available to aid clinicians in determining short-term prognoses in very severe COPD patients. Therefore, the present study was designed to provide a prospective assessment (1) of the mortality rates and (2) whether the baseline measurements may be determinants of 1-year mortality in hypoxemic COPD patients receiving long-term oxygen therapy (LTOT).Seventy-eight clinically stable patients with advanced COPD treated using LTOT were enrolled in a prospective cohort study. Outcome variable: first-year mortality. Baseline measurements: categorical variables: age (<60 or >= 60 years); gender; body mass index (<20 or >= 20 kg/m(2)); fat-free mass (FFM) index (<16 [men] and <15kg/m(2) [women]; baseline dyspnea index (BDI) (<= 3 or >3); and corticosteroid use. Continuous variables: smoking history; lung function; FFM; fat mass; hemoglobin; hematocrit; arterial blood gases; forearm muscle strength; St. George's Respiratory Questionnaire (SGRQ); and comorbidity score. By the end of 1-year of follow-up, 12 patients (15.4%) had died. Kaplan-Meier curves showed that BDI <= 3 was the only variable associated with higher mortality. Cox proportional hazards analysis revealed that tower PaO2 and SPO2, higher PaCO2 and SGRQ scores were associated with reduced survival. In the multivariate analysis, BDI remained predictive of mortality (hazard ratio [HR], 0.50; 95% confidence interval [CI], 0.31-0.81), as did PaO2 (HR, 0.49; 95% CI, 0.26-0.95). These data suggest that readily available parameters as dyspnea intensity and hypoxemia severity may be useful in predicting first-year survival rates in advanced COPD patients receiving LTOT (C) 2007 Elsevier Ltd.

Arnt van Tricht, gest. 1570, unterhielt bis in die späten 50er Jahre des 16. Jahrhunderts, wahrschein-lich aus Antwerpen kommend, in Kalkar am Niederrhein eine sehr erfolgreiche Werkstatt. Die bis dahin vorherrschende spätgotische Formensprache der langjährig ansässigen Bildhauer löste er durch die der Renaissance ab, führte jedoch deren Arbeitsfelder und Materialwahl weiter. Arnt van Tricht schuf Arbeiten sowohl religiöser als auch profaner Natur innerhalb des Gebiets der damals sehr bedeutenden Vereinigten Herzogtümer Kleve-Mark-Jülich-Berg und Geldern. Seine wohlhabenden Auftraggeber entstammten dem Klerus, der Bürgerschaft und dem Adel.rnIm Rahmen der Arbeit zeigte sich, dass sich für den Künstler die Verlegung der herzoglichen Residenz nach Düsseldorf und der wirtschaftliche Niedergang der Region letztlich stärker auswirkte als die religiösen Veränderungen durch die Reformation.rnArnt van Tricht schuf die meisten seiner religiösen Bildwerke für die Stiftskirche St. Viktor in Xanten, die durch die Bürgerschaft ausgestattete Pfarrkirche von St. Nicolai in Kalkar und umliegende Gemeinden. Einzelne Stücke sind, wohl über familiäre Verflechtungen vermittelt, in einem weiteren Radius zu finden. Van Tricht arbeitete Schnitzretabel mitsamt ihrer ornamentalen und figuralen Aus-stattung sowie Skulpturen(-gruppen) in Eichenholz. Daneben finden sich im Werk zahlreiche in Sandstein gearbeitete Skulpturen, die teilweise an Pfeilern und Portalen der Kirchen architektur-gebunden sind. Neben diesen rundplastischen Werken schuf Arnt van Tricht eine große Anzahl an steinernen Reliefarbeiten. Hierbei nehmen die überwiegend für die lokalen Kanoniker gearbeiteten Epitaphien mit biblischem Reliefbild in Ornamentrahmen den größten Teil ein.rnEin zweiter, gleichwertiger Werkkomplex, überwiegend in Sandstein gearbeitet, ist profaner Natur und fällt durch die Größe der Aufträge ins Gewicht. Arnt van Tricht war an einigen groß angelegten Modernisierungsprojekten an Stadthäusern und Kastellen des lokalen Adels beschäftigt. Für mehrere aufwendig gestaltete Fassadendekorationen arbeitete er Architekturglieder mit figürlicher Darstellung oder Ornament, Büsten und freiplastische Skulpturen. Arnt van Tricht war aber auch an der Aus-gestaltung der Innenräume beteiligt. Aufwendig skulptierte und reliefverzierte Kaminverkleidungen stehen dabei neben reduzierteren Arbeiten für offensichtlich weniger repräsentative Räume. Neben in Eichenholz gearbeiteter Vertäfelung schuf Arnt van Tricht hölzerne figurale Handtuchhalter. Diese zeigen, wie auch die Reliefbilder der Kamine, die darüber hinaus Wappen und Porträts der Bauherren aufnehmen, eine religiöse oder profane, auch antikisierende Thematik, bei der ein moralisierender Unterton mitschwingt.rnIn dieser Arbeit werden erstmals alle Werkstücke des Künstlers zusammengeführt dargestellt, so dass ein Werkkatalog mit einem Überblick über das sehr breit gefächerte Spektrum des Opus Arnt van Trichts vorliegt. Häufig durch bloße Nennung mit Arnt van Tricht in Verbindung gebrachte Arbeiten werden bewertet und die Zu- oder Abschreibung begründet. Auch können einige Stücke neu zugeschrieben werden.

BACKGROUND: Outcome after lung transplantation (LTx) is affected by the onset of bronchiolitis obliterans syndrome (BOS) and lung function decline. Reduced health-related quality of life (HRQL) and physical mobility have been shown in patients developing BOS, but the impact on the capacity to walk is unknown. We aimed to compare the long-term HRQL and 6-minute walk test (6MWT) between lung recipients affected or not by BOS Grade > or =2. METHODS: Fifty-eight patients were prospectively followed for 5.6 +/- 2.9 years after LTx. Assessments included the St George's Respiratory Questionnaire (SGRQ) and the 6MWT, which were performed yearly. Moreover, clinical complications were recorded to estimate the proportion of the follow-up time lived without clinical intercurrences after transplant. Analyses were performed using adjusted linear regression and repeated-measures analysis of variance. RESULTS: BOS was a significant predictor of lower SGRQ scores (p < 0.01) and reduced time free of clinical complications (p = 0.001), but not of 6MWT distance (p = 0.12). At 7 years post-transplant, results were: 69.0 +/- 21.8% vs 86.9 +/- 5.6%, p < 0.05 (SGRQ); 58.5 +/- 21.6% vs 88.7 +/- 11.4%, p < 0.01 (proportion of time lived without clinical complications); and 82.2 +/- 10.9% vs 91.9 +/- 14.2%, p = 0.27 (percent of predicted 6MWT), respectively, for patients with BOS and without BOS. CONCLUSIONS: Despite significantly less time lived without clinical complications and progressive decline of self-reported health status, the capacity to walk of patients affected by BOS remained relatively stable over time. These findings may indicate that the development of moderate to severe BOS does not prevent lung recipients from walking independently and pursuing an autonomous life.

Background Patients' health related quality of life (HRQoL) has rarely been systematically monitored in general practice. Electronic tools and practice training might facilitate the routine application of HRQoL questionnaires. Thorough piloting of innovative procedures is strongly recommended before the conduction of large-scale studies. Therefore, we aimed to assess i) the feasibility and acceptance of HRQoL assessment using tablet computers in general practice, ii) the perceived practical utility of HRQoL results and iii) to identify possible barriers hindering wider application of this approach. Methods Two HRQoL questionnaires (St. George's Respiratory Questionnaire SGRQ and EORTC QLQ-C30) were electronically presented on portable tablet computers. Wireless network (WLAN) integration into practice computer systems of 14 German general practices with varying infrastructure allowed automatic data exchange and the generation of a printout or a PDF file. General practitioners (GPs) and practice assistants were trained in a 1-hour course, after which they could invite patients with chronic diseases to fill in the electronic questionnaire during their waiting time. We surveyed patients, practice assistants and GPs regarding their acceptance of this tool in semi-structured telephone interviews. The number of assessments, HRQoL results and interview responses were analysed using quantitative and qualitative methods. Results Over the course of 1 year, 523 patients filled in the electronic questionnaires (1–5 times; 664 total assessments). On average, results showed specific HRQoL impairments, e.g. with respect to fatigue, pain and sleep disturbances. The number of electronic assessments varied substantially between practices. A total of 280 patients, 27 practice assistants and 17 GPs participated in the telephone interviews. Almost all GPs (16/17 = 94%; 95% CI = 73–99%), most practice assistants (19/27 = 70%; 95% CI = 50–86%) and the majority of patients (240/280 = 86%; 95% CI = 82–91%) indicated that they would welcome the use of electronic HRQoL questionnaires in the future. GPs mentioned availability of local health services (e.g. supportive, physiotherapy) (mean: 9.4 ± 1.0 SD; scale: 1 – 10), sufficient extra time (8.9 ± 1.5) and easy interpretation of HRQoL results (8.6 ± 1.6) as the most important prerequisites for their use. They believed HRQoL assessment facilitated both communication and follow up of patients' conditions. Practice assistants emphasised that this process demonstrated an extra commitment to patient centred care; patients viewed it as a tool, which contributed to the physicians' understanding of their personal condition and circumstances. Conclusion This pilot study indicates that electronic HRQoL assessment is technically feasible in general practices. It can provide clinically significant information, which can either be used in the consultation for routine care, or for research purposes. While GPs, practice assistants and patients were generally positive about the electronic procedure, several barriers (e.g. practices' lack of time and routine in HRQoL assessment) need to be overcome to enable broader application of electronic questionnaires in every day medical practice.

Latrepirdine (Dimebon) is a pro-neurogenic, antihistaminic compound that has yielded mixed results in clinical trials of mild to moderate Alzheimer's disease, with a dramatically positive outcome in a Russian clinical trial that was unconfirmed in a replication trial in the United States. We sought to determine whether latrepirdine (LAT)-stimulated amyloid precursor protein (APP) catabolism is at least partially attributable to regulation of macroautophagy, a highly conserved protein catabolism pathway that is known to be impaired in brains of patients with Alzheimer's disease (AD). We utilized several mammalian cellular models to determine whether LAT regulates mammalian target of rapamycin (mTOR) and Atg5-dependent autophagy. Male TgCRND8 mice were chronically administered LAT prior to behavior analysis in the cued and contextual fear conditioning paradigm, as well as immunohistological and biochemical analysis of AD-related neuropathology. Treatment of cultured mammalian cells with LAT led to enhanced mTOR- and Atg5-dependent autophagy. Latrepirdine treatment of TgCRND8 transgenic mice was associated with improved learning behavior and with a reduction in accumulation of Aβ42 and α-synuclein. We conclude that LAT possesses pro-autophagic properties in addition to the previously reported pro-neurogenic properties, both of which are potentially relevant to the treatment and/or prevention of neurodegenerative diseases. We suggest that elucidation of the molecular mechanism(s) underlying LAT effects on neurogenesis, autophagy and behavior might warranty the further study of LAT as a potentially viable lead compound that might yield more consistent clinical benefit following the optimization of its pro-neurogenic, pro-autophagic and/or pro-cognitive activities.
