Abstract
Abstract
Background
The estimated prevalence of anaemia on admission in the setting of acute coronary syndromes (ACS) is between 10 to 43% and up to 57% of the patients may develop hospital-acquired anaemia. The best blood transfusion strategy in anemic patients with symptomatic coronary syndromes remains unclear.
Purpose
We aimed to perform a systematic review and meta-analysis of randomized controlled trials (RCT) to assess the effect of different transfusion strategies in anemic patients with coronary syndromes on 30-day mortality, major adverse cardiovascular events (MACE), and non-cardiovascular complications.
Methods
We searched for all randomized trials comparing restrictive to conservativestrategy in patients with coronary syndromes published up to 16 th November 2021 on PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov without language, sample size, publication date or other data restrictions. All studies were assessed for bias using Cochrane risk of bias, and meta-analysed using a random effect model. The quality of evidence was evaluated by the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. The pre-specified primary outcome was all-cause death at 30 days. The secondary outcome was the composite of non-fatal recurrent myocardial infarction, non-fatal stroke, emergency revascularization, or cardiovascular death at 30 days (MACE). Safety endpoint was a combination of de novo or worsening congestive heart failure, stent thrombosis, venous thromboembolism, pneumonia, or blood stream infection.
Results
Three RCT (CRIT, MINT and REALITY) were included with 820 patients. The risk of bias was considered low, except for blinding of patients and healthcare professionals. Across the three studies, a total of 55 patients died in the first 30 days. We found no differences between restrictive transfusion strategy compared with liberal transfusion strategy in all-cause death at 30 days (risk ratio [RR]: 1.61, 95% confidence interval [CI] 0.38–6.90, I2=59%, MACE (RR: 1.16, 95% CI 0.49–2.71; I2=62%; figure 1) and incidence of adverse events (RR: 1.52, 95% CI 0.56–4.09; I2=60%; figure 2). The quality of evidence was considered low to moderate due to concerns of imprecision and inconsistency.
Conclusion(s)
Liberal and conservative strategies of blood transfusion show similar results in anaemic patients with symptomatic coronary syndromes. As blood is a scarce resource, our data support the current guideline recommendation of restrictive strategy of transfusion in anaemic patients with acute coronary syndromes.

Radiological Structured Report Integrated with Quantitative Imaging Biomarkers and Qualitative Scoring Systems. J Digit Imaging 2022; 35:396-407. [PMID: 35106674 PMCID: PMC9156634 DOI: 10.1007/s10278-022-00589-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Revised: 01/15/2022] [Accepted: 01/18/2022] [Indexed: 12/15/2022] Open
Abstract
The benefits of structured reporting (SR) in radiology are well-known and have been widely described. However, there are limitations that must be overcome. Radiologists may be reluctant to change the conventional way of reporting. Error rates could potentially increase if SR is used improperly. Interruption of the visual search pattern by keeping the eyes focused on the report rather than the images may increase reporting time. Templates that include unnecessary or irrelevant information may undermine the consistency of the report. Last, the lack of support for multiple languages may hamper the adaptation of the report to the target audience. This work aims to mitigate these limitations with a web-based structured reporting system based on templates. By including field validators and logical rules, the system avoids reporting mistakes and allows to automatically calculate values and radiological qualitative scores. The system can manage quantitative information from imaging biomarkers, combining this with qualitative radiological information usually present in the structured report. It manages SR templates as plugins (IHE MRRT compliant and compatible with RSNA's Radreport templates), ensures a seamless integration with PACS/RIS systems, and adapts the report to the target audience by means of natural language extracts generated in multiple languages. We describe a use case of SR template for prostate cancer including PI-RADS 2.1 scoring system and imaging biomarkers. For the time being, the system comprises 24 SR templates and provides service in 37 hospitals and healthcare institutions, endorsing the success of this contribution to mitigate some of the limitations of the SR.

Uncertainty and Bias in Global to Regional Scale Assessments of Current and Future Coastal Flood Risk. EARTH'S FUTURE 2021; 9:e2020EF001882. [PMID: 34435072 PMCID: PMC8365640 DOI: 10.1029/2020ef001882] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 05/12/2021] [Accepted: 06/01/2021] [Indexed: 05/21/2023]
Abstract
This study provides a literature-based comparative assessment of uncertainties and biases in global to world-regional scale assessments of current and future coastal flood risks, considering mean and extreme sea-level hazards, the propagation of these into the floodplain, people and coastal assets exposed, and their vulnerability. Globally, by far the largest bias is introduced by not considering human adaptation, which can lead to an overestimation of coastal flood risk in 2100 by up to factor 1300. But even when considering adaptation, uncertainties in how coastal societies will adapt to sea-level rise dominate with a factor of up to 27 all other uncertainties. Other large uncertainties that have been quantified globally are associated with socio-economic development (factors 2.3-5.8), digital elevation data (factors 1.2-3.8), ice sheet models (factor 1.6-3.8) and greenhouse gas emissions (factors 1.6-2.1). Local uncertainties that stand out but have not been quantified globally, relate to depth-damage functions, defense failure mechanisms, surge and wave heights in areas affected by tropical cyclones (in particular for large return periods), as well as nearshore interactions between mean sea-levels, storm surges, tides and waves. Advancing the state-of-the-art requires analyzing and reporting more comprehensively on underlying uncertainties, including those in data, methods and adaptation scenarios. Epistemic uncertainties in digital elevation, coastal protection levels and depth-damage functions would be best reduced through open community-based efforts, in which many scholars work together in collecting and validating these data.

Abstract
Background:Prior literature shows a global increase of cancer risk among patients with systemic sclerosis (SSc). Although breast cancer (BC) is one of the most frequent malignancies in SSc patients, the characteristics of this neoplasm among SSc patients is not well established and it is uncertain whether SSc significantly increases the risk of this cancer.Objectives:Describe the characteristics and risk factors for BC among Spanish patients with SSc.Methods:Ambispective and multicenter study of patients with a diagnosis of SSc according to ACR/EULAR criteria and/or LeRoy classification included in the Spanish Scleroderma Registry (RESCLE) from 2006 to 2018. Characteristics of patients with BC were described and incidence was compared with that of the general population.Results:Among 1930 patients with SSc, 206 (10.7%) had cancer. BC was the most frequent tumor location (47 patients of 206 with cancer [22.8%]), followed by lung cancer (29, 14.1%). The risk of BC was increased in patients with SSc compared to the general population (standardized incidence ratio [SIR] 1.31; 95% CI 1.10-1.54;P= 0.003).The comparison of patients with BC and those without cancer showed that patients with BC had older age at diagnosis of SSc (50.9 vs 45.9 years, respectively;P=0.004), were more frequently diagnosed of interstitial lung disease (ILD) (30/47 [63.8%] vs 694/1714 [40.5];P= 0.002) and pulmonary hypertension (12/24 [50.0%] vs 262/917 [28.6%];P= 0.037), had higher frequency of puffy hands as the first manifestation of SSc (4/45 [8.9%] vs 38/1664 [2.3 %];P= 0.023) and had more frequently primary biliary colangitis (PBC) (7 /46 [15.2%] vs 72 /1708 [4.2%];P= 0.004). Regarding autoimmunity profile, patients with SSc and BC had a significantly higher presence of anti-Ro (11/44 [25.0%] vs 214/1528 [14.0%];P= 0.049) and anti-mitochondrial antibodies (7/28 [25.0%] vs 96/837 [11.5%];P= 0.039). Multivariable regression analysis showed an independent association between the puffy hands (OR = 6.40; 95% CI 1.73-23.60;P= 0.005), diagnosis of PBC (OR = 5.70; 95% CI 2.16-15.07;P= 0.001), presence of ILD (OR = 3.29, 95% CI 1.69-6.39;P<0.001) and the presence of the anti-Ro antibody (OR 2.14; 95% CI 1.01-4.56;P= 0.048) with the presence of BC.Conclusion:BC risk was increased in patients with SSc. The development of ILD, PBC, the presence of anti Ro and puffy hands as the first clinical manifestation of SSc were identified as independent factors associated with the development of BC in our cohort.References:Colaci M et al.

Predictive performance of PAMG-1 vs fFN test for risk of spontaneous preterm birth in symptomatic women attending an emergency obstetric unit: retrospective cohort study. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2018; 51:644-649. [PMID: 28850753 DOI: 10.1002/uog.18892] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/26/2017] [Revised: 08/09/2017] [Accepted: 08/18/2017] [Indexed: 06/07/2023]
Abstract
OBJECTIVE To compare the performance of the placental alpha microglobulin-1 (PAMG-1) and fetal fibronectin (fFN) tests for the prediction of spontaneous preterm delivery in patients presenting to an emergency obstetric unit with threatened preterm labor, by conducting a retrospective audit of patient medical records from separate 1-year periods during which either fFN or PAMG-1 was used as the standard-of-care biochemical test. METHODS This was a retrospective cohort study based on chart review of electronic medical records of women with threatened preterm labor presenting at a level-III maternity hospital over two different periods: (1) the 'baseline' period (year 2012), during which the qualitative fFN test with a cut-off of 50 ng/mL was used as the standard-of-care biochemical test for the risk assessment of preterm delivery, and (2) the 'comparative' period (year 2016), during which the PAMG-1 test with a cut-off of 1 ng/mL was used as the standard-of-care biomarker test. Patients with a singleton pregnancy between 24 + 0 and 34 + 6 weeks' gestation with symptoms of early preterm labor, clinically intact membranes and cervical dilatation < 3 cm, who did not have a medically indicated preterm delivery within 14 days of testing, were selected for chart review and included in the analysis. Key parameters used for the analysis were biochemical test results, time of testing and time of delivery. Positive predictive value (PPV), negative predictive value (NPV), sensitivity, specificity, and positive and negative likelihood ratios (LR+ and LR-) for the prediction of spontaneous preterm delivery ≤ 7 and ≤ 14 days of presentation were calculated for the PAMG-1 and fFN tests. RESULTS Four hundred and twenty patients were identified as having presented with threatened preterm labor during the baseline period, of whom 378 (90.0%) met the eligibility criteria. Of these, 38 (10.1%) were fFN positive and 10 (2.6%) had spontaneous preterm delivery ≤ 7 days of presentation. PPV, NPV, LR+ and LR- of fFN were 7.9%, 97.9%, 3.2 and 0.8, respectively, for spontaneous preterm delivery ≤ 7 days. Four hundred and ten patients were identified as having presented with threatened preterm labor during the comparative period and 367 (89.5%) subjects met the eligibility criteria. Of these, 17 (4.6%) were PAMG-1 positive and 12 (3.3%) had spontaneous preterm delivery ≤ 7 days of presentation. PAMG-1 PPV and NPV were 35.3% and 98.3%, respectively, and LR+ and LR- were 16.1 and 0.5, respectively, for spontaneous preterm delivery ≤ 7 days. CONCLUSIONS Before switching to PAMG-1, fFN was the standard-of-care test for the risk assessment of spontaneous preterm delivery. This retrospective audit of each test's performance over separate 1-year periods shows that we were more than twice as likely to get a positive fFN test than a positive PAMG-1 test, while the rate of discharging women who ultimately delivered spontaneously within 14 days of testing was not affected. Furthermore, a positive PAMG-1 test was more than four times more reliable than a positive fFN test in predicting imminent spontaneous preterm delivery. The use of a more reliable biomarker that is associated with fewer false-positive results could lead to a reduction in unnecessary admissions, interventions and use of hospital resources.

Abstract
INTRODUCTION Alcohol consumption promotes inflammation through the Toll-like receptor 4 (TLR4)/nuclear factor (NF)-?B pathway, leading to organic damage. Some micro-RNA (miRNA) molecules modulate this inflammatory response by downregulating TLR4/NF-?B pathway mediators, like interleukins (ILs). Thus, polymorphisms within IL genes located near miRNA binding sites could modify the risk of ethanol-induced damage. The present study analyzed potential relationships between alcoholism or alcoholic liver disease (ALD) and IL12B 2124 G>T (rs1368439), IL16 5000 C>T (rs1131445), IL1R1 3114 C>T (rs3917328), and NFKB1 3400 A>G (rs4648143) polymorphisms. PATIENTS AND METHODS The study included 301 male alcoholic patients and 156 male healthy volunteers. Polymorphisms were genotyped using TaqMan® PCR assays for allelic discrimination. Allele and genotype frequencies were compared between groups. Logistic regression analysis was performed to analyze the inheritance model. RESULTS Analysis of the IL1R1 (rs3917328) polymorphism showed that the proportion of alleleT carriers (CT and TT genotypes) was higher in healthy controls (9.7%) than in alcoholic patients (6.5%; P=.042). However, multivariable logistic regression analyses did not yield a significant result. No differences between groups were found for other analyzed polymorphisms. CONCLUSIONS Our study describes, for the first time, the expected frequencies of certain polymorphisms within miRNA-binding sites in alcoholic patients with and without ALD. Further studies should be developed to clarify the potential relevance of these polymorphisms in alcoholism and ALD development.

Abstract
The origin of hypogonadism, a condition including both symptoms and biochemical criteria of androgen deficiency, in type 2 diabetes is poorly known. In a cross-sectional study of 267 unselected patients, we analyzed the potential correlation of several clinical and biochemical variables as well as chronic micro- and macrovascular diabetic complications with hypogonadism. Hypogonadism was present in 46 patients (17.2%) using a cutoff of total testosterone 10.4 nmol/L and in 31 (11.6%) with a cutoff of 8 nmol/L. Among these patients, hypogonadotropic hypogonadism was the most prevalent form (82.6%). Compared to eugonadal subjects, hypogonadal men had significantly lower glomerular filtration rate (67.1 ± 23.4 vs. 78.4 ± 24.6 mL/min/1.73 m2 , p = 0.005) and higher prevalence of chronic kidney disease (43.5% vs. 20.4%, p = 0.002), abnormal liver function tests (26.7% vs. 12%, p = 0.019), and psychiatric treatment (23.9% vs. 10.4%, p = 0.025). Total testosterone levels correlated inversely with age (R = -0.164, p = 0.007), fasting blood glucose (R = -0.127, p = 0.037), and triglycerides (R = -0.134, p = 0.029) and directly with glomerular filtration rate (R = 0.148, p = 0.015). Calculated free testosterone and bioavailable testosterone correlated directly with hemoglobin (R = 0.171, p = 0.015 and R = 0.234, p = 0.001, respectively). Multivariate logistic regression analysis, after adjusting for relevant confounding variables, showed that age >60 years (OR = 3.58, CI 95% = 1.48-8.69, p = 0.005), body mass index >27 kg/m2 (OR = 2.85, CI 95% = 1.14-7.11, p = 0.025), hypertriglyceridemia (OR = 2.16, CI 95% = 1.05-4.41, p = 0.035), glomerular filtration rate <60 mL/min/1.73 m2 (OR = 2.51, CI 95% = 1.19-5.29, p = 0.015), and abnormal liver function tests (OR = 3.57, CI 95% = 1.48-8.60, p = 0.005) were independently associated with male hypogonadism. Although older age, body mass index, and hypertriglyceridemia have been previously related to hypogonadism, our results describe that chronic kidney disease and abnormal liver function tests are independently correlated with hypogonadism in type 2 diabetic men.

Abstract
We describe a methodology to obtain three-dimensional models of engineered surfaces using scanning electron microscopy and multi-view photogrammetry (3DSEM). For the reconstruction of the 3D models of the surfaces we used freeware available in the cloud. The method was applied to study the surface roughness of metallic samples patterned with parallel grooves by means of laser. The results are compared with measurements obtained using stylus profilometry (PR) and SEM stereo-photogrammetry (SP). The application of 3DSEM is more time demanding than PR or SP, but it provides a more accurate representation of the surfaces. The results obtained with the three techniques are compared by investigating the influence of sampling step on roughness parameters.

Abstract
OBJECTIVES The purpose of this study was to develop a new brief, comprehensive geriatric assessment scale for older patients diagnosed with different hematological malignancies, the Geriatric Assessment in Hematology (GAH scale), and to determine its psychometric properties. MATERIALS AND METHODS The 30-item GAH scale was designed through a multi-step process to cover 8 relevant dimensions. This is an observational study conducted in 363 patients aged≥65years, newly diagnosed with different hematological malignancies (myelodysplasic syndrome/acute myeloblastic leukemia, multiple myeloma, or chronic lymphocytic leukemia), and treatment-naïve. The scale psychometric validation process included the analyses of feasibility, floor and ceiling effect, validity and reliability criteria. RESULTS Mean time taken to complete the GAH scale was 11.9±4.7min that improved through a learning-curve effect. Almost 90% of patients completed all items, and no floor or ceiling effects were identified. Criterion validity was supported by reasonable correlations between the GAH scale dimensions and three contrast variables (global health visual analogue scale, ECOG and Karnofsky), except for comorbidities. Factor analysis (supported by the scree plot) revealed nine factors that explained almost 60% of the total variance. Moderate internal consistency reliability was found (Cronbach's α: 0.610), and test-retest was excellent (ICC coefficients, 0.695-0.928). CONCLUSION Our study suggests that the GAH scale is a valid, internally reliable and a consistent tool to assess health status in older patients with different hematological malignancies. Future large studies should confirm whether the GAH scale may be a tool to improve clinical decision-making in older patients with hematological malignancies.

Abstract
Despite significant advancements over the years, there remains an urgent need for low cost diagnostic approaches that allow for rapid, reliable and sensitive detection of malaria parasites in clinical samples. Our previous work has shown that magnetic resonance relaxometry (MRR) is a potentially highly sensitive tool for malaria diagnosis. A key challenge for making MRR based malaria diagnostics suitable for clinical testing is the fact that MRR baseline fluctuation exists between individuals, making it difficult to detect low level parasitemia. To overcome this problem, it is important to establish the MRR baseline of each individual while having the ability to reliably determine any changes that are caused by the infection of malaria parasite. Here we show that an approach that combines the use of microfluidic cell enrichment with a saponin lysis before MRR detection can overcome these challenges and provide the basis for a highly sensitive and reliable diagnostic approach of malaria parasites. Importantly, as little as 0.0005% of ring stage parasites can be detected reliably, making this ideally suited for the detection of malaria parasites in peripheral blood obtained from patients. The approaches used here are envisaged to provide a new malaria diagnosis solution in the near future.

Systematic review with meta-analysis: the I148M variant of patatin-like phospholipase domain-containing 3 gene (PNPLA3) is significantly associated with alcoholic liver cirrhosis. Aliment Pharmacol Ther 2014; 40:571-81.

Abstract
BACKGROUND Several studies have reported an association between alcoholic liver cirrhosis (ALC) or other forms of alcoholic liver disease (ALD) and the genetic variant rs738409 (C>G) in adiponutrin/patatin-like phospholipase domain-containing 3 gene (PNPLA3). AIM To evaluate the influence of this variant on ALC and other forms of ALD. METHODS We performed a systematic review of previous studies on the relationship between rs738409 of PNPLA3 and ALD and meta-analysis was conducted in a random-effects model. Calculations of the odds ratios (ORs) and their confidence intervals (CIs), tests for heterogeneity and sensitivity analyses were performed. RESULTS Database search identified 11 previous studies available for inclusion with a total of 3495 patients with ALD (2087 with ALC) and 5038 controls (4007 healthy subjects and 1031 alcoholics without ALD). Patients with ALC compared to controls had a significantly higher prevalence of the G allele when comparing GG vs. CC (OR 4.30, 95% CI 3.25-5.69; P < 0.00001) or GC vs. CC genotypes (GC vs. CC: OR 1.91, 95% CI 1.67-2.17) or under a recessive or dominant model. Similar results were found when comparing separately patients with ALC vs. alcoholics without ALD or healthy subjects. An association of the G allele with ALD emerged when comparing ALD patients vs. alcoholics without ALD and/or healthy subjects although moderate to large heterogeneity was observed. Our data suggested an additive genetic model for this variant in ALD. CONCLUSION Our meta-analysis shows that the rs738409 variant of PNPLA3 is clearly associated with alcoholic liver cirrhosis.

Abstract
OBJECTIVE Short-stay units (SSUs) have been developed as an alternative to conventional hospitalisation. The aim of this study is to analyse the impact of short-stay units on the quality of medical care in Spain. MATERIAL AND METHODS A systematic review was performed by retrieving studies that analysed the results of SSUs in Spain, in terms of clinical effectiveness, efficiency and satisfaction among patients, using an electronic database search (Pubmed/Medline and Spanish Medical Index) and a review of selected references. The data collected included, mortality, length of stay and re-admission rates, as well as other variables. RESULTS Twenty-seven articles were found, with a great heterogeneity in both study design and type of SSU analysed. After analysing results, it was observed that SSUs in Spain provided effective clinical care. Low-quality evidence was also found supporting the hypothesis that SSUs are able to reduce overall length of stay in the whole hospital or department where they were created. There are not enough data to support any other advantages or benefits of SSUs, when compared with other hospitalisation units. CONCLUSIONS SSUs may be able to effectively improve clinical care in selected patients, and may help to shorten overall length of stay. Further research is needed in order to define their exact role and to establish their optimal model.

Abstract
The aim of the paper is to analyse the prevalence of liver involvement and related factors in HIV-infected patients with early syphilis (<2 years). Liver involvement was defined as an elevation above normal ranges of alanine transaminase, aspartate aminotransferase, gamma-glutamyltransferase and/or alkaline phosphatase during early syphilis, or doubling of previous levels in patients with liver enzyme elevation before syphilis. We undertook a multicentre study and of the 147 cases, 86.4% were men who had sex with men, and the diagnoses of syphilis and HIV infection were coincident in 48 (32.7%). Liver involvement was detected in 45 (30.6%) and the only related factor was a rapid plasma reagin (RPR) titre ≥1/64 (odds ratio 3.76; 95% confidence interval 1.3-10.5; P = 0.012). In conclusion, liver involvement occurs in around one-third of HIV-infected patients with early syphilis and is associated with high RPR levels. Syphilis should be included in the differential diagnosis of liver enzyme elevation in HIV-infected patients.

Abstract
OBJECTIVE To address the issue of sexual function and fertility in PUV patients. PATIENTS AND METHODS Of 47 patients (age > 18 years) treated for PUV in infancy 28 were contactable. They were sent a standard questionnaire requesting details on voiding dysfunction symptoms, and experience of erection, orgasm and ejaculation. RESULTS Of the 28, 16 (mean age 24 years) returned the questionnaire. Voiding frequency ranged from 3 to 10 times per day (mean = 5). Two patients had occasional mild diurnal incontinence but none had symptoms of overactivity. Three patients had a weak urinary stream. Renal function was normal in 9, 4 had a glomerular filtration rate <80 ml/min/1.73 m(2), and 3 had undergone renal transplant. Erections and orgasm were experienced by the 15 patients who responded to these questions, with 4 reporting mild or medium erectile dysfunction and 1, on dialysis, reporting slow ejaculation. Post-masturbation samples of semen and urine were collected from 6 patients. One had an alkaline pH, high percentage of immotile sperm and low sperm count. Another had a high concentration of abnormal forms, and seminal fluid was present in the urine of 3 patients. CONCLUSIONS In long-term follow-up, 44% of PUV patients develop chronic renal failure or end-stage renal disease, but bladder dysfunction symptoms are infrequent. Sexual function is mostly normal. Total semen counts and motility are compatible with paternity in most patients.

Abstract
OBJECTIVES To determine mortality and long-term survival factors in patients with systemic autoimmune diseases (SAD) admitted to the intensive care unit (ICU). METHODS Retrospective observational study including all consecutive patients with a diagnosis of any systemic autoimmune disease admitted to the medical ICU in a tertiary hospital between 1999 and 2007. Factors associated with reduced survival were identified by means of log rank test and backward stepwise Cox regression. RESULTS Thirty-seven patients (26 females) were included with median age being 44.3 years (interquartilic range [IQR]: 31.3). Sixteen (43.2%) patients had systemic lupus erythematosus, 9 (24.3%) had systemic vasculitis, 4 (10.8%) had systemic sclerosis and 4 (10.8%) had primary antiphospholipid syndrome. The main reason for ICU admission was autoimmune disease flare-up in 20 (54.0%) patients, followed by infections in 12 (32.4%). Median APACHE II at admission was 17 (IQR 7). At the end of follow-up, 15 (40.5%) patients died, 10 (27%) during hospitalisation (7 in the ICU) and 5 after hospital discharge. Factors associated with reduced long-term survival were: APACHE II score ≥18 (HR 6.02, 95% CI 1.76-20.62), age <45 years (HR 6.54, 95% CI 1.84-23.29), presence of any previous chronic disease (HR 18.20, 95% CI 3.72-88.96), and increase of corticosteroid therapy during ICU stay (HR 22.87, 95% CI 4.31-121.30). CONCLUSIONS The long-term survival of patients with systemic autoimmune diseases admitted to the ICU was related with age, higher APACHE II score, previous chronic diseases, and an increase in corticosteroids dose when comparing with previous ICU admissions.

Abstract
BACKGROUND Only a minority of alcoholics develop alcoholic liver disease (ALD) and allelic variants within genes encoding glutathione-S-transferases (GST) have been associated with ALD vulnerability with controversial results. AIM To assess the effects of GST polymorphisms on ALD by means of a genetic association study and meta-analysis. METHODS We retrieved published studies on the relationship between allelic variants within GST genes and ALD by means of electronic database search. A meta-analysis was conducted in a fixed or random effects model. Calculations of odds ratios (OR) and their confidence intervals (CI), tests for heterogeneity of the results and sensitivity analysis, have been performed. A genetic association study comparing GSTM1, GSTT1 and GSTP1 genotype distribution among 279 alcoholics with or without ALD and 144 controls was also performed. Results Fifteen previous studies were identified analysing the association of ALD with polymorphisms within GST genes. After meta-analysis, we found a significant association between the possession of the GSTM1 null allele and the presence of ALD (OR=1.43; 95% CI: 1.14, 1.78; P=0.002) among alcoholic patients. A significant association was also found for the possession of the GSTP1 Val/Val genotype and the presence of ALD (OR=2.04; 95% CI: 1.09, 3.80; P=0.03). CONCLUSIONS Our results suggest that, among alcoholics, carriers of GSTM1 null genetic variant or Val/Val genotype of Ile/Val GSTP1 polymorphism have an increased risk to suffer from alcoholic liver disease. The role of glutathione-S-transferase as a potential therapeutic target in alcoholic liver disease is reinforced.

Abstract
Infection is an important cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). This study was aimed at characterizing bloodstream infections in these patients and analysing factors associated with long term outcome. For this purpose, episodes of significant bacteraemia diagnosed from January 1991 to December 2006 among patients with SLE at a single centre were identified through a central database and clinical and analytical variables were recorded regarding short- and long-term follow-up. Univariate and multivariable analysis were performed to identify factors associated with long-term outcome. Thirty-eight SLE patients had 48 episodes of significant bacteraemia, with a 30-day mortality rate of 6.25%. Escherichia coli and Staphylococcus aureus were the leading Gram-negative and Gram-positive pathogens, respectively. After a median follow-up of 25 months, eight of these 38 patients (21.1%) had a further episode of bacteraemia and 13 of them (34.21%) died. Community-acquired bacteraemia and C reactive protein levels lower than 8 mg/dl during episodes were factors associated with lower long-term mortality. These results reinforce previous findings suggesting that lupus patients with bacteraemia episodes have poor long-term outcomes
