RESUMO
The diagnosis of Myelodysplastic syndromes (MDS) is frequently challenging, especially in terms of the distinction from the other non-neoplastic causes of cytopenia. Currently, it is based on the presence of peripheral blood cytopenias, peripheral blood and bone marrow dysplasia/blasts, and clonal cytogenetic abnormalities, but MDS diagnostic features are polymorphic and non-specific. We investigated the utility of complete blood count (CBC) and research parameters (RUO) from the analyzer BC 6800 Plus (Mindray Diagnostics) to discriminate MDS-related cytopenia. METHODS: 100 samples from healthy individuals were used to establish the values of research parameters in normal subjects. A retrospective study was conducted including 66 patients diagnosed with MDS, 90 cytopenic patients due to other diseases (cancer patients receiving therapy, aplastic anemia, other hematological malignancies) and 50 with macrocytic anemia. The Wilcoxon test was applied to detect statistical differences among the groups of patients, considering p < 0.05 significant. The diagnostic performance of the RUO parameters for discriminating MDS among cytopenias was evaluated using receiver operating characteristic (ROC) curve analysis. Amultivariable logistic regression model was performed to identify the potential predictors for having MDS. The area under curve (AUC) and the Hosmer-Lemeshow test of the model were assessed. The performance of the model was verified in a prospective study including 224 cytopenic patients (validation group). RESULTS: In the MDS group, the mean cell volume (MCV), percentage of macrocytic red cells (MAC), red cell distribution width (RDW) and immature platelets fraction (IPF) had increased values compared to the cytopenic and normal patients, while platelets, red and white cell counts, Neu X (related to the cytoplasmic complexity of neutrophils), Neu Y (related to nucleic acid content) and Neu Z (related to cell size) were lower (p < 0.001). Neu X, Neu Y, and Neu Z showed higher AUC for detecting MDS > 0.80; MAC, RDW and IPF AUC > 0.76. The multivariable model demonstrated that Neu X and Neu Y could be used in the recognition of MDS, AUC 0.88. In the validation group, 89.0% of the MDS patients were well classified. CONCLUSION: MDS are common malignant disorders with a poor prognosis, and early diagnosis is warranted for optimal benefit from treatment. RUO gain insights to detect dysplasia of MDS and could be used in the differential diagnosis of MDS from cytopenias of other etiologies.
RESUMO
PURPOSE: To identify 5-year survival prognostic variables in patients with colorectal cancer (CRC) and to propose a survival prognostic score that also takes into account changes over time in the patient's health-related quality of life (HRQoL) status. METHODS: Prospective observational cohort study of CRC patients. We collected data from their diagnosis, intervention, and at 1, 2, 3, and 5 years following the index intervention, also collecting HRQoL data using the EuroQol-5D-5L (EQ-5D-5L), European Organization for Research and Treatment of Cancer's Quality of Life Questionnaire-Core 30 (EORTC-QLQ-C30), and Hospital Anxiety and Depression Scale (HADS) questionnaires. Multivariate Cox proportional models were used. RESULTS: We found predictors of mortality over the 5-year follow-up to be being older; being male; having a higher TNM stage; having a higher lymph node ratio; having a result of CRC surgery classified as R1 or R2; invasion of neighboring organs; having a higher score on the Charlson comorbidity index; having an ASA IV; and having worse scores, worse quality of life, on the EORTC and EQ-5D questionnaires, as compared to those with higher scores in each of those questionnaires respectively. CONCLUSIONS: These results allow preventive and controlling measures to be established on long-term follow-up of these patients, based on a few easily measurable variables. IMPLICATIONS FOR CANCER SURVIVORS: Patients with colorectal cancer should be monitored more closely depending on the severity of their disease and comorbidities as well as the perceived health-related quality of life, and preventive measures should be established to prevent adverse outcomes and therefore to ensure that better treatment is received.

BACKGROUND: Previous data support that the inflammatory process underlying ulcerative colitis (UC) and Crohn's disease (CD) can start years before the diagnosis. The aim of this study was to determine if patients with an incidental diagnosis of UC or CD demonstrate an increase in healthcare utilization in the years preceding the symptomatic onset of the disease. METHODS: We performed a multicenter, retrospective, hospital-based, case-control study. Patients with an incidental diagnosis of UC or CD during the colorectal cancer screening program at 9 hospitals were included. Cases were matched 1:3 and compared separately with two control populations: one including healthy non-IBD subjects adjusted by gender, age, and date, excluding those with visits to Gastroenterology; and a second control cohort of UC/CD patients with symptomatic onset. RESULTS: A total of 124 patients with preclinical inflammatory bowel disease (IBD) were included (87 UC, 30 CD, 7 IBD unclassified; median age 56 years). Patients with preclinical IBD showed an increase in the number of visits to Primary Care up to 3 and 5 years before diagnosis (aIRR 1.59, 95% CI [1.37-1.86], p = 0.001; aIRR 1.43, 95% CI [1.24-1.67], p = 0.01) and more frequent use of steroids (aOR 2.84, 95% CI [1.21-6.69], p = 0.03; aOR 2.25, 95% CI [1.06-4.79], p = 0.04) compared to matched non-IBD healthy controls, respectively. In contrast, patients with a symptomatic onset visited Primary Care less frequently, but they had an increase in the number of visits to Emergency Department, specialist care, sick-leaves, CT/ultrasound examinations, and use of antibiotics or systemic steroids. CONCLUSIONS: There is an increased need for medical assistance and use of systemic steroids during the presymptomatic phase of IBD. These results will help in establishing new tools for early identification of IBD in the future.

BACKGROUND: Some quality indicators of proper health care in patients with colorectal cancer have been established. AIMS: Our goal was to evaluate the relationship between performing of certain procedures or treatments, included as quality indicators, and some outcomes of indicators in the follow-up of colorectal cancer patients. METHODS: This was a prospective cohort study of patients diagnosed with colorectal cancer that underwent surgery and were followed at 1, 2, 3, and 5 years. CT scanning, colonoscopy, chemotherapy, and radiotherapy were evaluated in relation to various clinical outcomes and PROM changes over 5 years. Multivariable generalized linear mixed models were used to evaluate their effect on mortality, complications, recurrence, and PROM changes (HAD, EQ-5D, EORTC-Q30) at the next follow-up. RESULTS: CT scanning or colonoscopy was related to a decrease in the risk of dying, while chemotherapy at a specified moment was related to an increased risk. In the case of recurrence, CT scanning and chemotherapy showed statistically increased the risk, while all the procedures and treatments influenced complications. Regarding PROM scales, CT scanning, colonoscopy, and radiotherapy showed statistically significant results with respect to an increase in anxiety and decrease in quality of life measured by the EORTC. However, undergoing radiotherapy at a specified moment increased depression levels, and overall, receiving radiotherapy decreased the quality of life of the patients, as measured by the EuroQol-5d. CONCLUSIONS: After adjustment for sociodemographic factors, comorbidities, and severity of the disease, performing certain quality indicators of proper health care in patients with colorectal cancer was related to less mortality but higher adverse outcomes.

OBJECTIVE: The prevalence of depressive symptoms immediately after the diagnosis of colorectal cancer (CRC) is high and has important implications both psychologically and on the course of the disease. The aim of this study is to analyse the association between depressive symptoms and CRC survival at 5 years after diagnosis. METHODS: This multicentre, prospective, observational cohort study was conducted on a sample of 2602 patients with CRC who completed the Hospital Anxiety and Depression Scale (HADS-D) at 5 years of follow-up. Survival was analysed using the Kaplan-Meier method and Cox regression models. RESULTS: According to our analysis, the prevalence of depressive symptoms after a CRC diagnosis was 23.8%. The Cox regression analysis identified depression as an independent risk factor for survival (HR = 1.47; 95% CI: 1.21-1.8), a finding which persisted after adjusting for sex (female: HR = 0.63; 95% CI: 0.51-0.76), age (>70 years: HR = 3.78; 95% CI: 1.94-7.36), need for help (yes: HR = 1.43; 95% CI: 1.17-1.74), provision of social assistance (yes: HR = 1.46; 95% CI: 1.16-1.82), tumour size (T3-T4: HR = 1.56; 95% CI: 1.22-1.99), nodule staging (N1-N2: HR = 2.46; 95% CI: 2.04-2.96), and diagnosis during a screening test (yes: HR = 0.71; 95% CI: 0.55-0.91). CONCLUSIONS: There is a high prevalence of depressive symptoms in patients diagnosed with CRC. These symptoms were negatively associated with the survival rate independently of other clinical variables. Therefore, patients diagnosed with CRC should be screened for depressive symptoms to ensure appropriate treatment can be provided.

PURPOSE: Health-related quality of life (HRQoL) measurement represents an important outcome in cancer patients. We describe the evolution of HRQoL over a 5-year period in colorectal cancer patients, identifying predictors of change and how they relate to mortality. METHODS: Prospective observational cohort study including colorectal cancer (CRC) patients having undergone surgery in nineteen public hospitals who were monitored from their diagnosis, intervention and at 1-, 2-, 3-, and 5-year periods thereafter by gathering HRQoL data using the EuroQol-5D-5L (EQ-5D-5L), European Organization for Research and Treatment of Cancer's Quality of Life Questionnaire-Core 30 (EORTC-QLQ-C30), and Hospital Anxiety and Depression Scale (HADS) questionnaires. Multivariable generalized linear mixed models were used. RESULTS: Predictors of Euroqol-5D-5L (EQ-5D-5L) changes were having worse baseline HRQoL; being female; higher Charlson index score (more comorbidities); complications during admission and 1 month after surgery; having a stoma after surgery; and needing or being in receipt of social support at baseline. For EORTC-QLQ-C30, predictors of changes were worse baseline EORTC-QLQ-C30 score; being female; higher Charlson score; complications during admission and 1 month after admission; receiving adjuvant chemotherapy; and having a family history of CRC. Predictors of changes in HADS anxiety were being female and having received adjuvant chemotherapy. Greater depression was associated with greater baseline depression; being female; higher Charlson score; having complications 1 month after intervention; and having a stoma. A deterioration in all HRQoL questionnaires in the previous year was related to death in the following year. CONCLUSIONS: These findings should enable preventive follow-up programs to be established for such patients in order to reduce their psychological distress and improve their HRQoL to as great an extent as possible. GOV IDENTIFIER: NCT02488161.

OBJECTIVE: The objective of this work is to evaluate the association of comorbidities with various outcomes in patients diagnosed with colon or rectal cancer. METHODS: We conducted a prospective cohort study of patients diagnosed with colon or rectal cancer who underwent surgery. Data were gathered on sociodemographic, clinical characteristics, disease course, and the EuroQol EQ-5D and EORTC QLQ-C30 scores, up to 5 years after surgery. The main outcomes of the study were mortality, complications, readmissions, reoperations, and changes in PROMs up to 5 years. Multivariable multilevel logistic regression models were used in the analyses. RESULTS: Mortality at some point during the 5-year follow-up was related to cardiocerebrovascular, hemiplegia and/or stroke, chronic obstructive pulmonary disease (COPD), diabetes, cancer, and dementia. Similarly, complications were related to cardiovascular disease, COPD, diabetes, hepatitis, hepatic or renal pathologies, and dementia; readmissions to cardiovascular disease, COPD, and hepatic pathologies; and reoperations to cerebrovascular and diabetes. Finally, changes in EQ-5D scores at some point during follow-up were related to cardiocerebrovascular disease, COPD, diabetes, pre-existing cancer, hepatic and gastrointestinal pathologies, and changes in EORTC QLQ-C30 scores to cardiovascular disease, COPD, diabetes, and hepatic and gastrointestinal pathologies. CONCLUSIONS: Optimising the management of the comorbidities most strongly related to adverse outcomes may help to reduce those events in these patients.

OBJECTIVE: To analyze the performance of adenosine deaminase in pleural fluid combined with other parameters routinely measured in clinical practice and assisted by machine learning algorithms for the diagnosis of pleural tuberculosis in a low prevalence setting, and secondly, to identify effusions that are non-tuberculous and most likely malignant. PATIENTS AND METHODS: We prospectively analyzed 230 consecutive patients diagnosed with lymphocytic exudative pleural effusion from March 2013 to June 2020. Diagnosis according to the composite reference standard was achieved in all cases. Pre-test probability of pleural tuberculosis was 3.8% throughout the study period. Parameters included were: levels of adenosine deaminase, pH, glucose, proteins, and lactate dehydrogenase, red and white cell counts and lymphocyte percentage in pleural fluid, as well as age. We tested six different machine learning-based classifiers to categorize the patients. Two different classifications were performed: a) tuberculous/non-tuberculous and b) tuberculous/malignant/other. RESULTS: Out of a total of 230 patients with pleural effusion included in the study, 124 were diagnosed with malignant effusion and 44 with pleural tuberculosis, while 62 were given other diagnoses. In the tuberculous/non-tuberculous classification, and taking into account the validation predictions, the support vector machine yielded the best result: an AUC of 0.98, accuracy of 97%, sensitivity of 91%, and specificity of 98%, whilst in the tuberculous/malignant/other classification, this type of classifier yielded an overall accuracy of 80%. With this three-class classifier, the same sensitivity and specificity was achieved in the tuberculous/other classification, but it also allowed the correct classification of 90% of malignant cases. CONCLUSION: The level of adenosine deaminase in pleural fluid together with cell count, other routine biochemical parameters and age, combined with a machine-learning approach, is suitable for the diagnosis of pleural tuberculosis in a low prevalence scenario. Secondly, non-tuberculous effusions that are suspected to be malignant may also be identified with adequate accuracy.

BACKGROUND: The aim of this study was to identify predictors of mortality in elderly patients undergoing colorectal cancer surgery and to develop a risk score. METHODS: This was an observational prospective cohort study. Individuals over 80 years diagnosed with colorectal cancer and treated surgically were recruited in 18 hospitals in the Spanish National Health Service, between June 2010 and December 2012, and were followed up 1, 2, 3, and 5 years after surgery. Sociodemographic and clinical data were collected. The primary outcomes were mortality at 2 and between 2 and 5 years after the index admission. RESULTS: The predictors of mortality 2 years after surgery were haemoglobin ≤ 10 g/dl and colon locations (HR 1.02; CI 0.51-2.02), ASA class of IV (HR 3.55; CI 1.91-6.58), residual tumour classification of R2 (HR 7.82; CI 3.11-19.62), TNM stage of III (HR 2.14; CI 1.23-3.72) or IV (HR 3.21; CI 1.47-7), LODDS of more than - 0.53 (HR 3.08; CI 1.62-5.86)) and complications during admission (HR 1.73; CI 1.07-2.80). Between 2 and 5 years of follow-up, the predictors were no tests performed within the first year of follow-up (HR 2.58; CI 1.21-5.46), any complication due to the treatment within the 2 years of follow-up (HR 2.47; CI 1.27-4.81), being between 85 and 89 and not having radiotherapy within the second year of follow-up (HR 1.60; CI 1.01-2.55), no colostomy closure within the 2 years of follow-up (HR 4.93; CI 1.48-16.41), medical complications (HR 1.61; CI 1.06-2.44), tumour recurrence within the 2 years of follow-up period (HR 3.19; CI 1.96-5.18), and readmissions at 1 or 2 years of follow-up after surgery (HR 1.44; CI 0.86-2.41). CONCLUSION: We have identified variables that, in our sample, predict mortality 2 and between 2 and 5 years after surgery for colorectal cancer older patients. We have also created risks scores, which could support the decision-making process. TRIAL REGISTRATION: ClinicalTrials.gov , NCT02488161 .

The factors that predispose an individual to a higher risk of death from COVID-19 are poorly understood. The goal of the study was to identify factors associated with risk of death among patients with COVID-19. This is a retrospective cohort study of people with laboratory-confirmed SARS-CoV-2 infection from February to May 22, 2020. Data retrieved for this study included patient sociodemographic data, baseline comorbidities, baseline treatments, other background data on care provided in hospital or primary care settings, and vital status. Main outcome was deaths until June 29, 2020. In the multivariable model based on nursing home residents, predictors of mortality were being male, older than 80 years, admitted to a hospital for COVID-19, and having cardiovascular disease, kidney disease or dementia while taking anticoagulants or lipid-lowering drugs at baseline was protective. The AUC was 0.754 for the risk score based on this model and 0.717 in the validation subsample. Predictors of death among people from the general population were being male and/or older than 60 years, having been hospitalized in the month before admission for COVID-19, being admitted to a hospital for COVID-19, having cardiovascular disease, dementia, respiratory disease, liver disease, diabetes with organ damage, or cancer while being on anticoagulants was protective. The AUC was 0.941 for this model's risk score and 0.938 in the validation subsample. Our risk scores could help physicians identify high-risk groups and establish preventive measures and better follow-up for patients at high risk of dying.ClinicalTrials.gov Identifier: NCT04463706.

BACKGROUND: Cementation of polyethylene liners into well-fixed cementless metal shells has become an option during revision total hip arthroplasty (THA). We report the results of cementing a dual-mobility (DM) component into a stable acetabular shell in high-risk patients undergoing revision THA. METHODS: A single-centre series of 10 patients undergoing revision THA with a DM cup cemented into an existing well-fixed shell between 2012 and 2016 were retrospectively reviewed. Failure due to aseptic loosening or instability and implant survival at last follow-up were analysed. The average age was 79.2 years and mean follow-up was 3.5 years. Indications were recurrent hip dislocation in 8 cases and intraoperative instability with moderate abductor insufficiency in 2 cases. In cases with recurrent dislocation, the aetiology of instability was classified by Wera type. RESULTS: At the latest follow-up, Harris Hip Scores had improved from 49.3 preoperatively to 71.3 postoperatively (p = 0.098). In the 8 patients with recurrent dislocation, 4 cases (50%) had an unclear aetiology (Wera type 6), 2 (25%) abductor deficiency (Wera type 3) and 2 (25%) late polyethylene wear (type 5).Postoperative recurrent dislocation occurred in 1 hip (10%). No cases of intraprosthetic dislocation, aseptic loosening of the previous shell or dissociation at the cement-cup interface were identified. CONCLUSION: Although the follow-up of this series is short, cementation of a DM cup into a previous well-fixed socket seems to be a viable option to treat and prevent instability after revision THA, without providing constraint at the cement-cup interface.

PURPOSE: 1 of the causes of groin pain after total hip arthroplasty (THA) is impingement of the iliopsoas tendon. The purpose of this study was to present our results with outside-in arthroscopic tenotomy for iliopsoas impingement after THA. METHODS: We retrospectively reviewed 12 patients treated between 2009 and 2016 with a minimum follow-up of 2 years. Anterior acetabular component prominence was measured on a true lateral hip radiograph. A transcapsular tenotomy was performed near the edge of the acetabular component through an outside-in arthroscopic approach. The primary clinical outcomes evaluated were groin pain, assessed with a visual analogue scale (VAS), and the Harris Hip Score (HHS). Secondary outcomes included strength of hip flexion, measured with the Medical Research Council (MRC) scale. RESULTS: All patients had groin pain improvement, though one patient continued to have moderate pain. The mean VAS score was significantly lower postoperatively (1.08) than preoperatively (6.2) (p < 0.001). The mean HHS improved from 58.8 (range, 37-76) to 86.1 (range, 59-98) (p = 0.001). The average postoperative MRC Scale was 4.58. The mean anterior prominence was 7.25 mm (range 3-12 mm). In patients with <10 mm of component prominence, tenotomy provided groin pain resolution in all cases (n = 8). In patients with ⩾10 mm of prominence, symptoms resolved in 3 out of 4 cases. CONCLUSIONS: Outside-in arthroscopic iliopsoas release provided a high rate of success with no complications in this study, even in patients with moderate acetabular component prominence.

OBJECTIVE: To identify factors associated with early, intermediate or late recurrence colon cancer recurrence. METHODS: A total of 1,732 consecutive patients with colon cancer were recruited and followed for a period of 5 years. Recurrence at 1 year (early), from 1 to 2 (early), from 2 to 3 (intermediate) and from 3 to 5 years (late) was the main outcome measures. RESULTS: Predictors of early recurrence (AUC (95% CI):0.74 (0.70-0.78) were as follows: TNM stage II and III, more than one type of invasion, haemoglobin <10 g/dl, residual tumour (R1), ASA IV, log odds of positive lymph nodes ratio ≥-0.53, perforation, neoadjuvant chemotherapy, infectious complications within 1 year and CEA pre- and post-intervention. These factors remained significant for predicting intermediate (AUC [95% CI]: 0.72 [0.67-0.77]) and late (AUC [95% CI]: 0.68 [0.63-0.74]) recurrence, except for ASA class, log lymph node ratio, perforation and neoadjuvant chemotherapy. Additionally, laterality (left) and medical complications up to 2 years were significant. CONCLUSIONS: These risk factors show good predictive ability of early, intermediate and late recurrence, confirming factors established by guidelines and adding some others. They could serve to provide more appropriate and accurate treatment and follow-up tailored to patient characteristics.

BACKGROUND: Few studies have examined gender differences in the clinical management of rectal cancer. We examine differences in stage at diagnosis and preoperative radiotherapy in rectal cancer patients. METHODS: A prospective cohort study was conducted in 22 hospitals in Spain including 770 patients undergoing surgery for rectal cancer. Study outcomes were disseminated disease at diagnosis and receiving preoperative radiotherapy. Age, comorbidity, referral from a screening program, diagnostic delay, distance from the anal verge, and tumor depth were considered as factors that might explain gender differences in these outcomes. RESULTS: Women were more likely to be diagnosed with disseminated disease among those referred from screening (odds ratio, confidence interval 95% (OR, CI = 7.2, 0.9-55.8) and among those with a diagnostic delay greater than 3 months (OR, CI = 5.1, 1.2-21.6). Women were less likely to receive preoperative radiotherapy if they were younger than 65 years of age (OR, CI = 0.6, 0.3-1.0) and if their tumors were cT3 or cT4 (OR, CI = 0.5, 0.4-0.7). CONCLUSIONS: The gender-specific sensitivity of rectal cancer screening tests, gender differences in referrals and clinical reasons for not prescribing preoperative radiotherapy in women should be further examined. If these gender differences are not clinically justifiable, their elimination might enhance survival.

INTRODUCTION: Aeromonas can cause several diseases in humans, with gastroenteritis accounting for most cases. The role of Aeromonas as a pathogen in human enterocolitis has been questioned in recent years. OBJECTIVE: To determine the incidence of gastrointestinal infection caused by Aeromonas in our area and its possible relationship to inflammatory bowel disease. PATIENTS AND METHODS: This was a retrospective observational study. All adult patients with a positive stool culture for Aeromonas were identified between January 2015 and December 2017 at Hospital Galdakao-Usansolo (Vizcaya, Spain). RESULTS: Ninety-eight patients were identified (median age 62 years; 51% women). Therefore, the incidence in our area was 32 cases per 105 inhabitants per year. Eleven per cent of them had been previously diagnosed with inflammatory bowel disease (four with ulcerative colitis and seven with Crohn's disease). Patients with inflammatory bowel disease more often received immunosuppressive therapy. Conversely, patients without inflammatory bowel disease suffered from more comorbidities. We also found comorbidity to be the risk factor most associated with Aeromonas infection. CONCLUSION: Aeromonas infection is a common gastrointestinal infection that may occur in both immunocompetent and immunocompromised patients. Immunosuppression is a significant factor in inflammatory bowel disease patients, while comorbidity seems to confer a higher risk on patients without this disease.

BACKGROUND: Tacrolimus is a calcineurin inhibitor commonly used for prophylaxis of rejection in renal and liver transplantation. There are limited but favourable data regarding its possible use in patients with inflammatory bowel disease (IBD). AIMS: To evaluate the efficacy and safety of tacrolimus in patients with IBD in clinical practice. METHODS: We performed a retrospective, multicentre study in 22 centres in Spain. All adult patients who received oral tacrolimus for luminal or perianal IBD were included. Clinical response was assessed by Harvey-Bradshaw index and partial Mayo score after 3 months. Perianal disease was evaluated by fistula drainage assessment. RESULTS: One hundred and forty-three patients were included (mean age 38 years; 51% male; median disease duration 110 months). In ulcerative colitis (UC) (n = 58), the partial Mayo score decreased after 3 months from median 6 to 3 (P = 0.0001), whereas in Crohn's disease (CD) (n = 85), the Harvey-Bradshaw index decreased after 3 months from median 9 to 7 (P = 0.011). In CD patients, blood tacrolimus concentrations during induction (>10 ng/mL vs <10 ng/mL; odds ratio 0.23, 95% CI 0.05-0.87) and the concomitant use of thiopurines (odds ratio 0.18, 95% CI 0.04-0.81) were associated with lower clinical disease activity at 3 months. Of 62 patients with perianal disease, complete closure was observed in 8% (n = 5) of patients with perianal fistulas, with 34% (n = 21) showing partial response. Treatment was maintained for a median of 6 months (IQR, 2-16). After a median clinical follow-up of 24 months (IQR, 15-57), the rate of treatment-related adverse events was 34%, correlating with blood drug concentrations (P = 0.021). Finally, 120 patients (84%) discontinued tacrolimus, usually due to absence or loss of response. Three patients (2%) were subsequently diagnosed with cancer. The overall rate of surgery was 39%, with a 33% colectomy rate in UC. CONCLUSIONS: Tacrolimus shows a clinical benefit in both CD and UC after 3 months of treatment, but its long-term effectiveness and frequent adverse events remain relevant issues in clinical practice.

PURPOSE: Demand for revision total hip arthroplasty (THA) is growing, and this type of surgery remains challenging for orthopedic surgeons. Our objectives were to assess clinical and radiographic outcomes, survivorship and complications with the SLR-Plus stem in revision THA. METHODS: We retrospectively reviewed 65 patients (66 hips) who had undergone revision THA with the SLR-Plus stem between 2008 and 2015 at two medical institutions with a minimum 2-year follow-up. The clinical outcome was assessed using the Harris hip score and the Merlé D'Aubigné score preoperatively and at final follow-up. A postoperative visual analogue scale for pain and satisfaction was also used. Radiographic subsidence and fixation, Kaplan-Meier survivorship and complications were analyzed. RESULTS: The mean follow-up was 4.1 years (SD 2.1). Aseptic loosening (57.6%) was the main indication for surgery. The mean Harris Hip Score improved from 50.4 (SD 16.5) to 83 (SD 12.7) (p < 0.001) and mean Merlé D'Aubigné score improved from 9.5 (SD 2.7) to 14.3 (SD 2.2) (p < 0.001). A total of 98.4% of stems showed radiographically stable fixation. No aseptic loosening of the stem was seen. Radiolucent lines > 1 mm were observed in 33.3% of stems. Three stems were re-revised: two due to infection and one due to instability. At 7 years, estimated stem survival was 95.5% for revision for any reason and 100% for revision for aseptic loosening. Dislocation occurred in 7.6% of hips. CONCLUSION: We have shown significant clinical improvement, 98.4% of stable fixation and 100% stem survivorship for aseptic loosening in revision THA with the SLR-Plus stem.

PURPOSE: Debridement, antibiotics and implant retention (DAIR) is commonly performed and widely accepted for the treatment of acute infections following hip arthroplasty. The aims of this study were to: i) determine the DAIR success rate in treating acute postoperative and hematogenous periprosthetic infections of the hip at a tertiary hospital, ii) identify possible outcome predictors, and iii) analyze clinical and radiological outcomes. MATERIALS AND METHODS: We retrospectively reviewed cases of acute postoperative (≤3 months from index procedure) and hematogenous periprosthetic infections following total hip arthroplasty treated with DAIR at our hospital between 2004 and 2015. Overall, 26 hips (25 patients) were included in the study, with a mean age of 72.5 years (standard deviation [SD], 9.4). The mean follow-up was 48.5 months (SD, 43.7). Several variables (e.g., patient characteristics, infection type, surgery parameters) were examined to evaluate their influence on outcomes; functional and radiographic outcomes were assessed. RESULTS: The overall success rate of DAIR was 26.9%. The male sex was associated with treatment failure (P=0.005) and debridement performed by a surgeon in hip unit with success (P=0.028). DAIR failure increased in patients with chronic pulmonary disease (P=0.059) and steroid therapy (P=0.062). Symptom duration of <11 days until DAIR yielded a better infection eradication rate (P=0.068). The mean postoperative Harris Hip Score was 74.2 (SD, 16.6). CONCLUSION: DAIR, despite being used frequently, had a high failure rate in our series. Outcomes improved if an experienced hip arthroplasty surgeon performed the surgery. Patient comorbidities and symptom duration should be considered for decision-making.
RESUMO
BACKGROUND: Debridement and irrigation with prosthetic retention followed by antibiotic therapy (DAIR) is one of the treatments of choice in acute infections after a total knee arthroplasty. However, the success rate varies widely in the literature, depending on several factors such as comorbidities of the patient, duration of infection, and microorganisms involved. The goal of this study was to assess the outcomes of this therapeutic option and to identify possible predictors of the result. METHODS: We retrospectively reviewed cases of acute postoperative (≤ 3 months from index procedure) and acute hematogenous periprosthetic knee infections treated with DAIR at our hospital between 2004 and 2016. Overall, 26 knees were included, with a mean age of 73.4 years. Several variables related to patient characteristics, infection type, and surgery were examined to evaluate their influence on outcome, and functional and radiographic outcome were assessed. The mean follow-up was 41 months. A descriptive analysis was carried out on the collected data, and a univariate analysis was performed with the objective of searching for influential factors in the resolution of the infection using the chi-square nonparametric test in the case of the categorical variables and the Wilcoxon test for the continuous ones. Moreover, univariate cox regression analysis was performed. RESULTS: The overall success rate was 77% at the last follow-up, recording a significantly greater cure in acute infections (93% acute vs 58% acute hematogenous, p = 0.03). The infections in which the Staphylococcus aureus was isolated had a significantly lower cure rate, with only 33% of success, compared to 82% of the non-aureus microorganisms (p < 0.05). CONCLUSIONS: The present study shows a considerable cure rate in the treatment of acute knee infections through DAIR, although patient comorbidities, type of infection, and causative microorganism should be considered for decision-making.
