Frequent coexistence of chronic heart failure and chronic obstructive pulmonary disease in respiratory and cardiac outpatients: Evidence from SUSPIRIUM, a multicentre Italian survey

Background Chronic heart failure (CHF) and chronic obstructive pulmonary disease (COPD) frequently coexist but concurrent COPD + CHF has been little investigated. Design This multicentre survey (SUSPIRIUM) was designed to evaluate: the prevalence of COPD in stable CHF and CHF in stable COPD; diagnostic/therapeutic work-up for concurrent COPD + CHF; clinical profile of patients with COPD + CHF; predictors of COPD in CHF and CHF in COPD. Methods A 5-month-long cross-sectional prospective observational survey was conducted in 10 cardiac and 10 respiratory connected outpatient units. Results The prevalence of CHF in the 378 surveyed COPD patients was 11.9% (95% confidence interval 8.8-16.6) and the prevalence of COPD in 375 CHF patients was 31.5% (95% confidence interval 26.8-36.4). Diagnostic tests for suspected comorbidity were prescribed in 21.6% and 22.9% of COPD and CHF patients, respectively. Patients with coexisting CHF + COPD had a higher incidence of hypertension, physical inactivity and more frequently a GOLD score of 3 or greater. Compared to CHF only, CHF + COPD patients were significantly older, more frequently smokers, at worse respiratory risk and in a higher New York Heart Association class. Conversely, hypercholesterolaemia, a family history of ischaemic heart disease, fluid retention and comorbidities were more frequent in COPD + CHF than COPD-only patients. At multivariate analysis, a GOLD score of 3 or greater in CHF strongly predicted coexistent COPD (odds ratio 8.985, P < 0.0001) as did a history of other respiratory diseases (5.184, P < 0.0001). A history of ischaemic heart disease (4.868, P < 0.0001), atrial fibrillation (3.302, P < 0.0001) and sedentary lifestyle (2.814, P < 0.004) predicted coexistent CHF in COPD. Conclusion The high prevalence of COPD + CHF calls for integrated disease management between cardiologists and pulmonologists. SUSPIRIUM identifies which cardiac/pulmonary outpatients should be screened for the respective comorbidity.

Distribution of phyllosilicates on the surface of Ceres

The dwarf planet Ceres is known to host phyllosilicate minerals at its surface, but their distribution and origin have not previously been determined. We used the spectrometer onboard the Dawn spacecraft to map their spatial distribution on the basis of diagnostic absorption features in the visible and near-infrared spectral range (0.25 to 5.0 micrometers). We found that magnesium- and ammonium-bearing minerals are ubiquitous across the surface. Variations in the strength of the absorption features are spatially correlated and indicate considerable variability in the relative abundance of the phyllosilicates, although their composition is fairly uniform. These data, along with the distinctive spectral properties of Ceres relative to other asteroids and carbonaceous meteorites, indicate that the phyllosilicates were formed endogenously by a globally widespread and extensive alteration process.

High prevalence of fragility vertebral fractures in patients hospitalised in Internal Medicine Units. Results of the POINT (Prevalence of Osteoporosis in INTernal medicine) study

BACKGROUND

Osteoporotic vertebral fractures (VFs) often go unrecognised in both healthy individuals and in pathological conditions. Few data exist on VFs in patients hospitalised in Internal Medicine Units (IMUs), who often suffer from multiple concomitant chronic disorders.

AIM OF THE STUDY

This multicentre cross-sectional study was aimed at assessing the prevalence of VFs in an unselected population of patients referring to IMUs. Correlations between VFs and the main coexisting diseases were also investigated.

METHODS

Information on demographic, clinical and laboratory findings, and on the presence of known risk factors for osteoporosis was recorded. The Genant's semi-quantitative method was used to evaluate, in a central reading centre, the presence and severity of VFs in the thoracic and lumbar spine.

RESULTS

A cohort of 995 patients was evaluated. At least one VF of any grade was found in 47.5% of patients, with similar prevalence between females (48.1%) and males (46.7%). Older age, chronic obstructive pulmonary disease, and previous diagnosis of osteoporosis showed a significant association with VFs in multivariable analysis. However, 79.7% of the VFs were observed in patients without previous diagnosis of osteoporosis. Moreover, a VF of grade 2 or greater was found in 20.8% of patients.

CONCLUSIONS

Fragility VFs is a very frequent finding in patients hospitalised in IMUs. Consequently, more attention should be devoted in this clinical setting to this comorbidity, which is known to be an additional factor for mortality and, when localised in the thoracic part of the spine, may negatively influence a concomitant respiratory insufficiency.

Cometary science. The organic-rich surface of comet 67P/Churyumov-Gerasimenko as seen by VIRTIS/Rosetta

The VIRTIS (Visible, Infrared and Thermal Imaging Spectrometer) instrument on board the Rosetta spacecraft has provided evidence of carbon-bearing compounds on the nucleus of the comet 67P/Churyumov-Gerasimenko. The very low reflectance of the nucleus (normal albedo of 0.060 ± 0.003 at 0.55 micrometers), the spectral slopes in visible and infrared ranges (5 to 25 and 1.5 to 5% kÅ(-1)), and the broad absorption feature in the 2.9-to-3.6-micrometer range present across the entire illuminated surface are compatible with opaque minerals associated with nonvolatile organic macromolecular materials: a complex mixture of various types of carbon-hydrogen and/or oxygen-hydrogen chemical groups, with little contribution of nitrogen-hydrogen groups. In active areas, the changes in spectral slope and absorption feature width may suggest small amounts of water-ice. However, no ice-rich patches are observed, indicating a generally dehydrated nature for the surface currently illuminated by the Sun.

Italian Survey on Prevalence and Disease Management of Chronic Heart Failure and Chronic Obstructive Pulmonary Disease comorbidity in ambulatory patients. SUSPIRIUM study rationale and design

BACKGROUND

Chronic heart failure (CHF) and chronic obstructive pulmonary disease (COPD) are leading causes of morbidity and mortality worldwide. Through shared risk factors and pathophysiological mechanisms, CHF and COPD frequently coexist. The concurrent disease has important therapeutic implications and independently predicts worsened mortality, impaired functional status, and health service use. However, assessment of the comorbidity varies widely according to the population studied, diagnostic criteria and measurement tools applied. Both syndromes have been studied extensively but largely separately, mostly in the domain of the pulmonologist for COPD and in the domain of the cardiologist for CHF.

STUDY OBJECTIVES AND DESIGN

The aim of the study is to evaluate in an Italian outpatients setting (10 cardiology and 10 pulmonology centers from the same institution) the prevalence, clinical profile and the routine diagnostic, functional and therapeutic work-up applied by cardiologists and pulmonologists in the presence/suspicion of concurrent disease in patients in a stable phase of their disease. For this purpose, CHF and COPU outpatients will be enrolled in a multicenter, nationwide, prospective observational study. Risk estimation of comorbidity will be based on suspected, documented or patient-reported diagnosis of COPD/CHF. In the absence of documented concurrent diagnosis, each specialist will describe the diagnostic, functional and therapeutic work-up applied.

CONCLUSION

The design of the study focused on the diagnostic validation of the CHF-COPD comorbidity aims to provide relevant new information on the assessment of the coexistent condition in the cardiac and pulmonary outpatients setting and on specialty-related different diagnostic and therapeutic strategies of comorbidity utilized in real life clinical practice. The symptomatic and prognostic benefits resulting from a combined approach to CHF/COPD could outweigh those attainable by treating either condition alone.

Candidemia in Neurosurgical Intensive Care Unit: preliminary analysis of the effect of topical Nystatin prophylaxis and adequate source control on patients with early tracheostomy intubation

INTRODUCTION

The present study represents a preliminary evaluation of the impact of topical nystatin prophylaxis administration and adequate CVC management on reducing the chance of developing candidemia in neurosurgical intensive care unit (NICU) patients.

MATERIALS AND METHODS

We conducted a case-control study at the nine bed NICU of the Policlinico "Umberto I" teaching hospital in Rome, Italy, during the period from January 2011 to July 2012. We compared eight patients with culture proven Candida bloodstream infection (CBSI) with a control group of 19 patients who did not have evidence of CBSI.

RESULTS

When the CBSI group was compared with the control group, the former were more likely than controls to not have received nystatin prophylaxis and adequate catheter care (p= 0,008). When CBSI group was matched with patients with no adequate source control and nystatin prophylaxis, average NICU stay (71.13 days vs 19.0 days) was significant (mean difference = -52.12 days, 95% CI -97.11 to -7.14, p= 0.028). The same was true for mean time of glucocorticoid exposure (mean difference = -10.5 days, 95% CI -17.35 to -3.65, p<0.01). Binary logistic regression analysis demonstrated no significant association between topical nystatin prophylaxis (p= 0.99), length of NICU stay (p= 0.99), time of glucocorticoid exposure (p= 0.99) and candidemia.

CONCLUSION

Topical prophylaxis with nystatin and adequate source control proved to be effective in preventing invasive candidiasis in patients admitted to the NICU.

Spectroscopic characterization of mineralogy and its diversity across Vesta

The mineralogy of Vesta, based on data obtained by the Dawn spacecraft's visible and infrared spectrometer, is consistent with howardite-eucrite-diogenite meteorites. There are considerable regional and local variations across the asteroid: Spectrally distinct regions include the south-polar Rheasilvia basin, which displays a higher diogenitic component, and equatorial regions, which show a higher eucritic component. The lithologic distribution indicates a deeper diogenitic crust, exposed after excavation by the impact that formed Rheasilvia, and an upper eucritic crust. Evidence for mineralogical stratigraphic layering is observed on crater walls and in ejecta. This is broadly consistent with magma-ocean models, but spectral variability highlights local variations, which suggests that the crust can be a complex assemblage of eucritic basalts and pyroxene cumulates. Overall, Vesta mineralogy indicates a complex magmatic evolution that led to a differentiated crust and mantle.

Unique expression pattern of human nicotinamide mononucleotide adenylyltransferase isozymes in red blood cells

Nicotinamide mononucleotide adenylyltransferase (NMNAT) catalyzes the formation of nicotinamide adenine dinucleotide (NAD). In humans, three isozymes have been identified: NMNAT1, which is widely expressed in all tissues, NMNAT2 and NMNAT3, which show a tissue-specific expression and whose mRNA levels are generally lower compared to NMNAT1. In the present study we determined the individual NMNAT isozymes activity in human red blood cells (RBCs) by using a biochemical discrimination assay based on the distinctive catalytic properties of the three proteins. We found that isozyme 3 predominates over isozyme 1, whereas isozyme 2 is absent. This high prevalence of NMNAT3 is cell-aging independent and was also confirmed by analyzing the mRNA and protein levels. RBC represent the first human cell type with a remarkable predominance of NMNAT3, and this unique expression pattern is discussed in light of the catalytic properties of the isozymes and in consideration of the biochemical microenvironment of RBC.

WldS can delay Wallerian degeneration in mice when interaction with valosin-containing protein is weakened

Axon degeneration is an early event in many neurodegenerative disorders. In some, the mechanism is related to injury-induced Wallerian degeneration, a proactive death program that can be strongly delayed by the neuroprotective slow Wallerian degeneration protein (Wld(S)) protein. Thus, it is important to understand the Wallerian degeneration mechanism and how Wld(S) blocks it. Wld(S) location is influenced by binding to valosin-containing protein (VCP), an essential protein for many cellular processes including membrane fusion and endoplasmic reticulum-associated degradation. In mice, the N-terminal 16 amino acids (N16), which mediate VCP binding, are essential for Wld(S) to protect axons, a role which another VCP binding sequence can substitute. In Drosophila, the Wld(S) phenotype is weakened by a similar N-terminal truncation and by knocking down the VCP homologue ter94. Neither null nor floxed VCP mice are viable so it is difficult to confirm the requirement for VCP binding in mammals in vivo. However, the hypothesis can be tested further by introducing a Wld(S) missense mutation, altering its affinity for VCP but minimizing the risk of disturbing other aspects of its structure or function. We introduced the R10A mutation, which weakens VCP binding in vitro, and expressed it in transgenic mice. R10AWld(S) fails to co-immunoprecipitate VCP from mouse brain, and only occasionally and faintly accumulates in nuclear foci for which VCP binding is necessary but not sufficient. Surprisingly however, axon protection remains robust and indistinguishable from that in spontaneous Wld(S) mice. We suggest that either N16 has an additional, VCP-independent function in mammals, or that the phenotype requires only weak VCP binding which may be driven forwards in vivo by the high VCP concentration.

NAD(P) biosynthesis enzymes as potential targets for selective drug design

NAD(P) biosynthetic pathways can be considered a generous source of enzymatic targets for drug development. Key reactions for NAD(P) biosynthesis in all organisms, common to both de novo and salvage routes, are catalyzed by NMN/NaMN adenylyltransferase (NMNAT), NAD synthetase (NADS), and NAD kinase (NADK). These reactions represent a three-step pathway, present in the vast majority of living organisms, which is responsible for the generation of both NAD and NADP cellular pools. The validation of these enzymes as drug targets is based on their essentiality and conservation among a large variety of pathogenic microorganisms, as well as on their differential structural features or their differential metabolic contribution to NAD(P) homeostasis between microbial and human cell types. This review describes the structural and functional properties of eubacterial and human enzymes endowed with NMNAT, NADS, and NADK activities, as well as with nicotinamide phosphoribosyltransferase (NamPRT) and nicotinamide riboside kinase (NRK) activities, highlighting the species-related differences, with emphasis on their relevance for drug design. In addition, since the overall NMNAT activity in humans is accounted by multiple isozymes differentially involved in the metabolic activation of antineoplastic compounds, their individual diagnostic value for early therapy optimization is outlined. The involvement of human NMNAT in neurodegenerative disorders and its role in neuroprotection is also discussed.

In-hospital symptomatic venous thromboembolism and antithrombotic prophylaxis in Internal Medicine. Findings from a multicenter, prospective study

Hospitalised medical patients are at increased risk of venous thromboembolism (VTE), but the incidence of hospitalisation-related VTE in unselected medical inpatients has not been extensively studied, and uncertainties remain about the optimal use of thromboprophylaxis in this setting. Aims of our prospective, observational study were to assess the prevalence of VTE and the incidence of symptomatic, hospitalisation-related events in a cohort of consecutive patients admitted to 27 Internal Medicine Departments, and to evaluate clinical factors associated with the use of thromboprophylaxis. Between March and September 2006, a total of 4,846 patients were included in the study. Symptomatic VTE with onset of symptoms later than 48 hours after admission ("hospital-acquired" events, primary study end-point) occurred in 26 patients (0.55%), while the overall prevalence of VTE (including diagnosis prior to or at admission) was 3.65%. During hospital stay antithrombotic prophylaxis was administered in 41.6% of patients, and in 58.7% of those for whom prophylaxis was recommended according to the 2004 Guidelines of the American College of Chest Physicians. The choice of administering thromboprophylaxis or not appeared qualitatively adherent to indications from randomised clinical trials and international guidelines, and bed rest was the strongest determinant of the use of prophylaxis. Data from our real-world study confirm that VTE is a relevant complication in patients admitted to Internal Medicine Departments, and recommended tromboprophylaxis is still under-used, in particular in some patients groups. Further efforts are needed to better define risk profile and to optimise prophylaxis in the heterogeneous setting of medical inpatients.

Clinical features of bacterial meningitis in Italy: a multicenter prospective observational study

We carried out a prospective observational study on clinical features of bacterial meningitis. Between October 2002 and June 2005, 322 adult bacterial meningitis cases in 49 infectious disease wards in Italy (MENTORE study group) were enrolled in the study. 133 cases were due to Streptococcus pneumoniae, 44 to Neisseria meningitidis and 145 to other microorganisms. A high SAPS score and coma on admission, as well as need for mechanical ventilation, were more frequent in the pneumococcal meningitis group. Neurological impairment was present in 151 out of 311 patients, and was more frequent in pneumococcal meningitis. A single antibiotic was employed in only 90 of 315 cases; a combination of ceftriaxone and ampicillin was the most frequently administered treatment. Ceftriaxone was also the single most used drug. Adjunctive treatment with steroids was administered in 210 out of 303 patients for a median duration of 7 days. Median duration of fever was 4 days, and median hospital stay was 16 days; hospitalization was significantly longer in the pneumococcal meningitis group. At discharge, neurological impairment was still present in 59 (21%) of 277 patients. Twenty (6.9%) out of 289 patients died during hospitalization. Distribution of adverse outcome (death and neurological impairment) in patients treated with or without steroids and within different time zones between onset of symptoms and commencement of antibiotics was studied; a trend toward a worse prognosis was seen in patients treated more than 24 hours after onset of the disease.In our study, infectious disease clinicians made extensive use of steroids as adjuvant therapy for bacterial meningitis, even in absence of detailed national and local guidelines. Mortality seemed to be lower in comparison with the literature.

Activity of chemotherapy in mucinous ovarian cancer with a recurrence free interval of more than 6 months: results from the SOCRATES retrospective study

BACKGROUND

Mucinous ovarian carcinoma have a poorer prognosis compared with other histological subtypes. The aim of this study was to evaluate, retrospectively, the activity of chemotherapy in patients with platinum sensitive recurrent mucinous ovarian cancer.

METHODS

The SOCRATES study retrospectively assessed the pattern of care of a cohort of patients with recurrent platinum-sensitive ovarian cancer observed in the years 2000-2002 in 37 Italian centres. Data were collected between April and September 2005. Patients with recurrent ovarian cancer with > 6 months of platinum free interval were considered eligible.

RESULTS

Twenty patients with mucinous histotype and 388 patients with other histotypes were analyzed. At baseline, mucinous tumours differed from the others for an higher number of patients with lower tumor grading (p = 0.0056) and less advanced FIGO stage (p = 0.025). At time of recurrence, a statistically significant difference was found in performance status (worse in mucinous, p = 0.024). About 20% of patients underwent secondary cytoreduction in both groups, but a lower number of patients were optimally debulked in the mucinous group (p = 0.03). Patients with mucinous cancer received more frequently single agent platinum than platinum based-combination therapy or other non-platinum schedules as second line therapy (p = 0.026), with a response rate lower than in non-mucinous group (36.4% vs 62.6%, respectively, p = 0.04). Median time to progression and overall survival were worse for mucinous ovarian cancer. Finally, mucinous cancer received a lower number of chemotherapy lines (p = 0.0023).

CONCLUSION

This analysis shows that platinum sensitive mucinous ovarian cancer has a poor response to chemotherapy. Studies dedicated to this histological subgroup are needed.

Home non-invasive mechanical ventilation and long-term oxygen therapy in stable hypercapnic chronic obstructive pulmonary disease patients: comparison of costs

BACKGROUND

A cost analysis of nocturnal non-invasive ventilation (NNV) in stable chronic obstructive pulmonary disease (COPD) patients would be helpful in decision making, when the balance between the increased demand and the availability of resources should be checked.

OBJECTIVES

Based on data from the Italian trial in stable hypercapnic COPD patients, this study compares the cost of care associated with the use of NNV when added to the usual long-term oxygen therapy (LTOT) with the cost of care of LTOT regimen alone.

METHODS

Cost was calculated in 77 of 90 patients included into that trial. Analysis included drug therapy, hospitalisations due to acute exacerbation, oxygen and ventilator equipment. An estimation of charges was made according to the national sources of cost for drugs and hospital admissions and the actualised reimbursement for the home care provided to both oxygen and ventilator users. The cost/day comparison was made between the individual patients in the 2 groups (NNV + LTOT, n = 35; LTOT, n = 42).

RESULTS

The mean cost of drugs and oxygen was similar in both groups, whereas the cost of hospitalisation tended to be lower in NNV + LTOT compared to LTOT alone (8.25 +/-10.29 vs. 12.50 +/- 20.28 EUR/patient/day, p < 0.05). Inclusion of the ventilator equipment increased the total cost to 23.73 EUR/day in the NNV + LTOT compared to 21.42 EUR/day in the LTOT group (not significant).

CONCLUSIONS

The present report suggests that long-term management with addition of non-invasive ventilation does not increase costs compared with the usual LTOT regimen: the hospital-related costs were reduced when using the ventilator in these hypercapnic COPD patients.

Extending the platinum-free interval with a non-platinum therapy in platinum-sensitive recurrent ovarian cancer. Results from the SOCRATES Retrospective Study

BACKGROUND

It has been proposed that extending the platinum-free interval with intervening non-platinum therapy increases the efficacy of a later re-treatment with platinum in platinum-sensitive recurrent ovarian cancer. This hypothesis is based on data from small series and although it has not been validated prospectively, this strategy has entered general practice in Italy in the last years. The SOCRATES study retrospectively assessed the pattern of care of a cohort of patients with recurrent platinum-sensitive ovarian cancer observed in the years 2000-2002 in 37 Italian centres. Data were collected between April and September 2005.

METHODS

Patients with recurrent ovarian cancer with a platinum-free interval >6 months were eligible. 493 patient files were collected and 428 were eligible and analyzed.

RESULTS

The interval from the end of the 1st line to relapse was 6-12 months in 164 patients (39.5%) and >12 months in 251 cases (60.5%). Patients received a 2nd (100%), 3rd (80.1%), 4th (50.2%), 5th (28.3%), and 6th (11.9%) line of chemotherapy. At 2nd line 282 (65.9%) received platinum (group A), while 146 (34.1%) received non-platinum chemotherapy (group B). In the latter group, 67 patients received platinum at later progression (group B1), while 79 never received platinum (group B2). Median time to platinum re-treatment was 20 and 23.1 months in patients of groups A and B1, respectively. The response rate to the first platinum received was 74.4 and 57.4% in groups A and B1, respectively (p = 0.02). Group B2 was characterized by the worst response rate and survival. At multivariate analysis time of first platinum re-treatment (2nd line vs. later; p = 0.0132; OR = 2.34) and age (p = 0.0029; OR = 2.41) was independently associated with a higher possibility of response to platinum.

CONCLUSIONS

With the limits of a retrospective study, our data question the hypothesis that extending the platinum-free interval with an intervening non-platinum therapy in patients with recurrent platinum-sensitive ovarian cancer improves the response rate of a further platinum re-treatment.

End-of-life decision-making in respiratory intermediate care units: a European survey

A survey was performed on behalf of the European Respiratory Society to assess end-of-life practices in patients admitted to European respiratory intermediate care units and high dependency units over a 6-month period. A 33-item questionnaire was sent by e-mail to physicians throughout Europe and the response rate was 28 (29.5%) out of 95. A total of 6,008 patients were admitted and an end-of-life decision was taken in 1,292 (21.5%). The mortality rate in these patients was 68% (884 out of 1,292). The patients received similar proportions of withholding of treatment (298 (23%) out of 1292), do-not-resuscitate or do-not-intubate orders (442 (34%) out of 1,292) and noninvasive mechanical ventilation as the ceiling of ventilatory care (402 (31%) out of 1,292). Withdrawal of therapy was employed in 149 (11%) out of 1,292 patients and euthanasia in one. Do-not-intubate/do-not-resuscitate orders were more frequently used in North compared with South Europe. All of the 473 competent patients directly participated in the decision, whereas, in 722 (56%) out of 1,292 cases, decision-making was reported to be shared with the nurses. In European respiratory intermediate care units and high dependency units, an end-of-life decision is taken for 21.5% of patients admitted. Withholding of treatment, do-not-intubate/do-not-resuscitate orders and noninvasive mechanical ventilation as the ventilatory care ceiling are the most common procedures. Competent patients are often involved, together with nurses.

Management of patients with nonvariceal upper gastrointestinal hemorrhage before and after the adoption of the Rockall score, in the Italian Gastroenterology Units

OBJECTIVES

Nonvariceal upper gastrointestinal hemorrhage is a frequent reason for ordinary hospital admission. In Italy the use of prognostic scores to stratify the risk has not been adequately validated: the impact on clinical management of a rating system like the Rockall score remains to be established. RING is a 'register' that has been collecting hospital discharge files from hospital gastroenterology units, giving a broad picture of the patients admitted for this pathology.

METHODS

We analyzed the hospital discharge files collected between 2001 and 2005 from 12 gastroenterology units, which issued more than 26,000 hospital discharge files for ordinary hospital admission and have been using the Rockall score for defining nonvariceal upper gastrointestinal hemorrhage since 2003.

RESULTS

There were 2832 hospital discharge files with a main diagnosis of nonvariceal upper gastrointestinal hemorrhage: 1335 'before' the Rockall score was introduced, 1497 'after' the introduction. Patients' mean age was 67.7+/-16.7 years, with a male/female ratio of 1.7 and no significant changes over the years. There were no differences in the distribution of diagnoses in nonvariceal upper gastrointestinal hemorrhage patients before/after the introduction of the Rockall score, though the mean hospital stay became shorter (7.1+/-5.0 vs. 6.3+/-4.5 days), and mortality declined (2.8 vs. 2.3%), in parallel with the caselist as a whole. For 1102 ordinary hospital admission Rockall score was calculated. Diagnoses were more accurate: significantly fewer undefined causes and an increase in peptic ulcer. The mean Rockall score was 4.6+/-2.2: 17.8% low (0-2), 48.7% intermediate (3-5), and 33.5% high (>or=6). Mean hospital stay, rebleeding, and mortality were correlated with the severity of the score.

CONCLUSION

The Rockall score enables the clinician to formulate a more precise diagnosis and substantially shortens the time in hospital, especially for patients at low-risk of rebleeding and death, so more resources can be dedicated to critically ill patients.

Seasonal patterns of hospital treatment for inflammatory bowel disease in Italy

AIM

It is still debated whether clinical flare-ups of chronic inflammatory bowel disease follow a seasonal pattern, and the various reports are based on general practitioners' records or hospital discharge charts. There are, however, no specific figures for treatment in hospital gastroenterology units, which serve as a reference point for these disorders. This study was therefore designed to investigate whether there is a seasonal pattern in admissions for inflammatory intestinal disease in Italy, differing from what is generally known about gastrointestinal pathologies, since there are no nation-wide figures on the subject.

METHODS

The RING (Ricerca Informatizzata in Gastroenterologia) project is an observational study collecting hospital discharge forms from 22 centers in Italy.

RESULTS

From winter 2000 to autumn 2003, the 22 gastroenterology units participating in the RING project discharged 32,357 patients following ordinary hospital admissions. Of these, 2,856 (8.8%) had a main diagnosis of inflammatory bowel disease: 1,541 Crohn's disease, and 1,315 ulcerative colitis. No seasonal patterns were detected for either category, or when the analysis was done by age, sex and site of disease.

CONCLUSIONS

The most serious flare-ups of inflammatory bowel disease, i.e. those requiring routine hospital treatment, do not appear to follow any seasonal pattern, regardless of the site of the disease or the patient's age or sex.

Extending the platinum-free interval (PFI) with a non-platinum therapy in platinum (P)- sensitive recurrent ovarian cancer (OC): Results from the SOCRATES retrospective study

5093

Background: Chance of response to P is correlated to PFI (Markman, J Clin Oncol 1991). It has been proposed that extending PFI by interposing non-P therapy increase activity of delayed P retreatment in patients (pts) with P-sensitive recurrent OC, but this strategy is based on data from small series. The SOCRATES study retrospectively assessed the pattern of treatment of a cohort of pts with P-sensitive recurrent OC. Methods: Data of pts treated between 2000 and 2002 at 37 centers were collected in 2005. Pts with recurrent OC were eligible if P-sensitive [interval from end of first line to relapse (RFI) > 6 months]. Results: Data on chemotherapy at relapse were available in 428 pts. RFI was 6–12 months in 40% and >12 months in 60%. Pts received a 2nd (100%), 3rd (80%), 4th (50%), 5th (28%), 6th (12%) line of chemotherapy. 282 pts (65.9%) received P at first relapse (Group A) after a median RFI of 19 months, with a 74.4% response rate (RR) out of 246 evaluable pts. 67 pts (15.7%) received non-P at first relapse after a median RFI of 9.6 months, with a RR of 44.6% out of 56 evaluable pts, and then received P at later relapse after a median PFI of 23 months, with a 57.4% RR out of 47 evaluable pts (Group B). 79 pts (18.5%), with a median RFI of 8.4 months, had a on-P 2nd line with a RR of 28.8% out of 66 evaluable pts, and never received P later (Group C). The difference in RR to P given as 2nd line and delayed P is statistically significant (p = 0.02, Fisher exact test). Median overall survival was 27.2, 26.1 and 16.8 months for Group A, B and C, respectively. Conclusions: With the limits of a retrospective study, our data show that, although P was given in the group B after a similar PFI than in the group A, due to the interposition of a non-P therapy, activity of P was higher when given immediately after relapse than when postponed at subsequent lines. Overall, these data suggest that P-sensitive pts should receive P as soon as possible, and delaying it may preclude the chance of receiving the best treatment. (Study sponsored by GlaxoSmithKline).
