Introduction: Most patients evaluated for suspected pulmonary embolism(PE) conclude the Emergency Department(ED) work-up with a diagnosis of PE not confirmed(PE excluded;PE-E). We aimed to investigate the clinical features, short and long-term mortality, and prognostic factors for death in elderly with PE-E, and to compare these figures with those of patients with PE confirmed(PE-C). Methods: Consecutive patients ≥65 years old evaluated in the ED for clinically suspected hemodynamically stable acute PE were included in this retrospective cohort study. Results: Study population: 657 patients with suspected PE, PE-C:162(24.65%). When compared with PE-C, patients with PE-E presented a higher prevalence of chronic cardiopulmonary disease (17.37% vs 8.02%, p = 0.003), a lower prevalence of pulse rate >110 (13.13% vs 25.93%; p0 was associated with higher short and long-term mortality (30-day:HR:5.31,p = 0.029; 5 year:HR:2.18, p < 0.001), meanwhile comorbidity (Charlson Comorbidity Index>0) only with higher long-term mortality (30-day: HR:1.60, p = 0.342; 5 year: HR:1.41, p = 0.038). Conclusion: In real world haemodinamically stable elderly patients evaluated in the ED for suspected PE, short and long-term mortality was markedly high regardless whether PE was confirmed or excluded. At the time to set management and follow up strategies, elderly patients with PE excluded should not be considered a low-risk population.

RATIONAL: People with cystic fibrosis carrying residual function (RF) mutations are considered to have a mild disease course. This may influence caregivers and patients on how intensive the treatments should be.OBJECTIVES: Characterize disease severity of patients carrying RF mutations, using the European CF Society Patient Registry (ECFSPR) data.METHODS: Demographic, clinical characteristics, lung function and death probability of patients carrying at least one RF mutation were analyzed and compared to patients homozygous to minimal function mutations (MF).MAIN RESULTS: Of the 44,594 eligible patients (median age 19.5 years, IQR 10-29.8), 6,636 (14.6%) carried RF mutations, and 37,958 (85.1%) MF mutations. Patients carrying RF mutations were older, diagnosed at a later age, had lower sweat chloride at diagnosis and better FEV1pp at each age group. However, their FEV1pp declined with age and rates of chronic Pseudomonas aeruginosa increased with age. A significant number of patients with RF had FEV1pp similar to patients with MF at each age group. 4.5% of RF patients were treated with oxygen and 2.61% had a lung transplant. With increasing age, 26.6% of RF patients were treated with pancreatic enzymes associated with a more severe lung disease. RF patients had shortened life spans, with mortality starting around the age of 20 years.CONCLUSIONS: Patients carrying an RF mutations experience a decline of pulmonary function with age, leading to life-shortening. Standard of care therapies and augmenting CFTR function may improve their survival and quality of life.

COVID-19 pandemic in its early months has deeply influenced rheumatic patients’ follow-up in terms of treatment adherence, disease control achieved with treat-to-target and tight-control strategies. Nationwide mitigation strategies such as confinement, travel restrictions and inadequate access to routine visits catalysed the rapid switch to remote rheumatologic consultations as an attempt to partially compensate for the decline of in-person outpatient visits. This observational retrospective study was conducted to establish if the hybrid of in-person and telephone tight-control approach activated by our rheumatology unit in Milan (Italy) during the first lockdown (LD) period has been effective in maintaining remission in patients with rheumatoid arthritis (RA) treated with targeted therapies and to identify potential factors associated with its maintenance. Data were extracted from a longitudinal observational registry (Eethics Committee 138_1999) including consecutive adult patients with RA treated with biologic or targeted synthetic drugs. During the first pandemic wave, before the visit, rheumatologists provided virtual care handled by telephone to assess the clinical status and to guarantee the absence of current contraindications to therapy. After tele counselling, based on the care required, patients …

Background: Viral infections can cause significant morbidity in cystic fibrosis (CF). The current Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic could therefore have a serious impact on the health of people with CF (pwCF). Methods: We used the 38-country European Cystic Fibrosis Society Patient Registry (ECFSPR) to collect case data about pwCF and SARS-CoV-2 infection. Results: Up to 30 June 2020, 16 countries reported 130 SARS-CoV-2 cases in people with CF, yielding an incidence of 2.70/10 0 0 pwCF. Incidence was higher in lung-transplanted patients (n = 23) versus non transplanted patients (n = 107) (8.43 versus 2.36 cases/10 0 0). Incidence was higher in pwCF versus the age-matched general population in the age groups < 15, 15-24, and 25-49 years (p < 0.001), with similar trends for pwCF with and without lung transplant. Compared to the general population, pwCF (regardless of transplantation status) had significantly higher rates of admission to hospital for all age groups with available data, and higher rates of intensive care, although not statistically significant. Most pwCF recovered (96.2%), however 5 died, of whom 3 were lung transplant recipients. The case fatality rate for pwCF (3.85%, 95% CI: 1.26-8.75) was non-significantly lower than that of the general population (7.46%; p = 0.133). Conclusions: SARS-CoV-2 infection can result in severe illness and death for pwCF, even for younger patients and especially for lung transplant recipients. PwCF should continue to shield from infection and should be prioritized for vaccination. (c) 2021 The Authors. Published by Elsevier B.V. on behalf of European Cystic Fibrosis Society.

Introduction The prognostic accuracy of D-dimer for risk assessment in acute Pulmonary Embolism (APE) patients may be hampered by comorbidities. We investigated the impact of comorbidity burden (CB) by using the Charlson Comorbidity Index (CCI), on the prognostic ability of D-dimer to predict 30 and 90-day mortality in hemodynamically stable elderly patients with APE. Methods All patients aged >65 years with normotensive APE, consecutively evaluated in the Emergency Department since 2010 through 2014 were included in this retrospective cohort study. Area under the curve (AUC) and ½ Net Reclassification Improvement (NRI) were calculated. Results Study population: 162 patients, median age: 79.2 years. The optimal cut-off value of CCI score for predicting mortality was ≤1 (Low CB) and >1 (High CB), AUC = 0.786. Higher levels of D-dimer were associated with an increased risk death at 30 (HR = 1.039, 95%CI:1.000–1.080, p = 0.049) and 90 days (HR = 1.039, 95%CI:1.009–1.070, p = 0.012). When added to simplified Pulmonary Embolism Severity Index (sPESI) score, D-dimer increased significantly the AUC for predicting 30-day mortality in Low CB (AUC = 0.778, 95%CI:0.620–0.937, ½NRI = 0.535, p = 0.015), but not in High CB patients (AUC = 0.634, 95%CI:0.460–0.807, ½ NRI = 0.248, p = 0.294). Similarly, for 90-day mortality D-dimer increased significantly the AUC in Low CB (AUC = 0.786, 95%CI:0.643–0.929, ½NRI = 0.424, p-value = 0.025), but not in High CB patients (AUC = 0.659, 95%CI:0.541–0.778, ½NRI = 0.354, p-value = 0.165). Conclusion In elderly patients with normotensive APE, comorbidities condition the prognostic performance of D-dimer, which was found to be a better predictor of death in subjects with low CB. These results support multimarker strategies for risk assessment in this population.

Objective We aimed to study in SSc patients macrovascular involvement by using power Doppler ultrasound (PDUS) and microvascular one by PDUS and nailfold video-capillaroscopy (NVC) and to examine the association between history of digital ulcers (HDU) and imaging (PDUS and NVC) parameters. Methods NVC and PDUS were systematically performed in 106 consecutive SSc patients at the 3rd and 4th finger of the dominant hand after exclusion of ulnar artery occlusion (UAO). 22 MHz PDUS measurements included nailbed and fingertip qualitatively graded, and resistivity index (RI) of ulnar and radial proper digital arteries. Capillary number/mm was calculated by NVC on the same digits examined by PDUS. Results Vascularization at fingertip and nailbed showed a good correlation between them and to capillary number. RI, representative of macrovascular involvement, did not correlate to microvascular involvement as assessed by PDUS and NVC. RI and capillary number at NVC showed significant correlation to HDU while fingertip and nailbed vascularization as assessed by PDUS did not. As such, PDUS and NVC provide different and potentially complementary information on SSc-related peripheral macro- and micro-vascular involvement. Conclusion Macro- and micro-vascular involvement in SSc patients are different processes and are not present at the same time in every patient. Thus, both these aspects should be carefully evaluated in SSc patients.

Warfarin-related nephropathy is an unexplained acute kidney injury, and may occur in patients with supratherapeutic INR, in the absence of overt bleeding. Similar findings have been observed in rats treated with dabigatran etexilate. We conducted a prospective study in dabigatran etexilate-treated patients to assess the incidence of dabigatran-related nephropathy and to investigate the possible correlation between dabigatran plasma concentration (DPC) and worsening renal function. One hundred and seven patients treated long term with dabigatran etexilate for non-valvular atrial fibrillation (NVAF) were followed up for 90 days. DPC, serum creatinine (SCr) and serum cystatin C were prospectively measured. Ninety five patients had complete follow-up data and were evaluable for primary endpoint. Eleven patients had supratherapeutic DPC, defined as DPC higher than 200 ng/ml at study enrolment, but at the end of follow-up no patient showed a persistent increase in SCr. No patients experienced acute kidney injury. Our study shows that no persistent renal detrimental effect is associated with dabigatran treatment. An increase in SCr during dabigatran treatment is reversible and it seems to be unrelated to dabigatran itself.

BACKGROUND Emerging evidence suggests an association between COVID‐19 and acute pulmonary embolism (APE). AIMS To assess the prevalence of APE in patients hospitalized for non‐critical COVID‐19 who presented clinical deterioration, and to investigate the association of clinical and biochemical variables with a confirmed diagnosis of APE in these subjects. METHODS All consecutive patients admitted to the internal medicine department of a general hospital with a diagnosis of non‐critical COVID‐19, who performed a Computer Tomography Pulmonary Angiography (CTPA) for respiratory deterioration in April 2020, were included in this retrospective cohort study. RESULTS Study populations: 41 subjects, median(IRQ)age:71.7(63‐76)years, CPTA confirmed APE=8(19.51%,CI95%:8.82%‐34.87%). Among patients with and without APE, no significant differences were found with regards symptoms, comorbidities, treatment, Wells score and outcomes. The optimal cut‐off value of D‐dimer for predicting APE was 2454 ng/mL, sensitivity(CI95%):63(24‐91), specificity:73(54‐87), Positive Predictive Value:36(13‐65), Negative Predictive Value: 89(71‐98) and AUC:0.62(0.38‐0.85). The standard and age‐adjusted D‐dimer cut‐offs, and the Wells score >2 did not associate with confirmed APE, albeit a cut‐off value of D‐dimer=2454 ng/mL showed an RR:3.21;CI95%:0.92‐13.97;p=0.073. Heparin at anticoagulant doses was used in 70.73% of patients before performing CTPA. CONCLUSION Among patients presenting pulmonary deterioration after hospitalization for non‐critical COVID‐19, the prevalence of APE is high. Traditional diagnostic tools to identify high APE pre‐test probability patients do not seem to be clinically useful. These results support the use of a high index of suspicion for performing CTPA to exclude or confirm APE as the most appropriate diagnostic approach in this clinical setting.

Inhaled therapies are relatively simple and easy to be managed however ineffective use of aerosols when self-administered may occur. We described variation of the number of clinic visits, lung function and number of antibiotic courses performed over 12 months in participants with cystic fibrosis (CF), when supervised or not by physiotherapists (PTs) at home. Participants in 8 Italian CF centers with a prescription of dry-powder antibiotic choose whether to be supervised at home (PT-FU) or not (non-PT-FU), in adjunct to routine clinic visits. PTs assisted participants with their inhaled therapies regimen and reviewed the airway clearance program in use. Mixed-effect regression models were fitted to evaluate the variation of selected endpoints over time. A total of 163 participants were included. Lung function declined over time in both groups, at higher extent in the non-PT-FU group at 6 months (-1.8, 95%CI: -4.4 to 0.7 % predicted), without reaching statistical significance, whereas in the PT-FU group only, nearly one visit less was recorded (p=0.027). Regardless the type of supervision adopted, the number of antibiotic courses did not change compared to the previous year. We counted 19/90 (21.1%) drop-out in the PT-FU, double compared to the group followed up at the clinics (p=0.065). Participants under a course of an inhaled antibiotic therapy showed a 1-year decline in lung function, whereas only the group receiving home supervision counted nearly one visit less at the CF center, whose clinical relevance should be further discussed.

BackgroundMedian survival for cystic fibrosis (CF) patients in Europe is unknown and is likely to be influenced by socioeconomic factors. Using the European CF Society Patient Registry (ECFSPR), median survival estimates were obtained for CF patients across Europe and the impact of socioeconomic status on survival was examined.MethodsCF subjects known to be alive and in the ECFSPR between 2010 and 2014 were included. Survival curves were estimated using the Kaplan–Meier method. Differences in the survival curves were assessed using the log-rank test. Cox regression was used to estimate the association between socioeconomic factors and the age-specific hazard of death, with adjustment for sex, age at diagnosis, CF transmembrane conductance regulator (CFTR) genotype and transplant status.ResultsThe final analysis included 13 countries with 31 987 subjects (135 833 person-years of follow-up) and 1435 deaths. Median survival age for these patients in the ECFSPR was 51.7 (95% CI 50.0–53.4) years. After adjusting for potential confounders age at diagnosis, sex, CFTR genotype and transplant status, there remained strong evidence of an association between socioeconomic factors and mortality (pConclusionsMedian survival for patients with CF in Europe is comparable to that reported in other jurisdictions and differs by socioeconomic factors.

Background Monitoring changes in the epidemiology of cystic fibrosis (CF) pathogens is essential for clinical research, quality improvement, and clinical management. Methods We analyzed data reported to the European Cystic Fibrosis Society Patient Registry (ECFSPR) from 2011 to 2016 to determine the overall and the age-specific annual prevalence and incidence of selected CF pathogens and their trends during these years. The ECFSPR collects data on three chronic infections: Pseudomonas aeruginosa (PsA), Burkholderia cepacia complex Species (BCC) and Staphylococcus aureus (SA), as well as on the occurrence of non-tuberculous mycobacteria (NTM) and Stenotrophomonas maltophilia (SM). The same analyses were performed for different country groups, according to their gross national income (GNI). Results The pathogens with the highest prevalence were SA and PsA, with prevalence, in 2016, equal to 38.3% and 29.8% respectively, followed by SM (8.1%). The pathogens with the lowest prevalence were NTM (3.3%) and BCC (3.1%). The overall prevalence and incidence significantly decreased for PsA; they also decreased for BCC, while they increased significantly for SA. The overall prevalence of NTM and SM increased significantly. The most considerable prevalence changes were observed for PsA, which decreased across all income country groups and all age strata (with the exception of 0–1 years) The prevalence and incidence of pathogens differed significantly according to GNI. Conclusions The epidemiology of CF pathogens in Europe has changed; epidemiologic data differ significantly among countries with different socio-economic status. The causes of these observations are multifactorial and include improvements in clinical care and infection control.

BACKGROUND: A1006E is a Cystic Fibrosis (CF) mutation that is still not widely known. We report phenotypic features and geographic distribution of the largest cohort of people with CF (pwCF) carrying A1006E to date. METHODS: Study of European pwCF carrying A1006E mutation, included in the European CF Society Patient Registry (ECFSPR). Genotype, ancestries and all variables recorded were compared to a cohort of F508del/F508del patients. Rate of decline in percentage-of-predicted FEV(1) (ppFEV(1)) was also analyzed using the 2010-2017 ECFSPR. RESULTS: 44 pwCF carrying A1006E were reported (59% males), median age 33 years old (3-58), 54.5% Spanish and 40.9% Italian, most with ancestry in Murcia (Spain) and Lazio (Italy) regions. Compared to F508del homozygous, A1006E-pwCF were significantly older (75% vs. 52.5% = 18 years old) and diagnosed at later median age (6.98 vs. 0.29 years); showed lower rates of meconium ileus (2.33% vs. 17.7%), pancreatic insufficiency (27.91% vs. 99.26%), diabetes (2.33% vs. 21.98%), liver disease (6.98% vs. 36.72%) and Pseudomonas aeruginosa chronic colonization (30.95% vs. 42.51%); and presented better nutrition (BMI z-score 0.44 vs. -0.43) and ppFEV(1) (90.8% vs. 78.6%), with 18.9% (most >40 years old) having a ppFEV(1)

The assessment of planned discharges: agreement between BRASS index and clinical judgement.The BRASS (Blaylock Risk Assessment Screening Score) index is a risk screening tool for identification of patients at risk of difficult discharge.To assess the agreement of discharge options between the BRASS classification and the nurses' clinical judgement.Consecutive patients admitted to surgical wards of a large Italian hospital from November 2016 to June 2017 were assessed with the BRASS index within 48 hours from admission and 24 hours before discharge. After discharge a group of expert nurses, blind to the BRASS score and patient effective destination, planned the patients' discharge reviewing the clinical records. Patients were classified as needing ordinary discharge, with support or to hospital.The 90% of the 428 included patients remained in the same BRASS risk class; the agreement between BRASS score (K Cohen) at admission and clinical judgement was 0.474 and 0.533 at discharge. Of the 96 subject at need of discharge with support or to hospital, 60 were classified in the same class by the BRASS Index. Factors that impacted on the different classification were patients' age, presence of devices and availability and appropriateness of social support.Most patients remained in the same BRASS class. There is moderate agreement between BRASS index and clinical judgement, specifically for patients at medium/high risk of difficult discharge. Our data confirm the need for including new items in the Brass scale.

Elderly patients presenting with acute pulmonary embolism (PE) frequently have significant underlying comorbidities which may condition the prognosis. The current study aimed to determine the ability of Charlson comorbidity index (CCI) score to predict short and long-term mortality in elderly patients with hemodynamically stable acute PE. All hemodynamically stable patients aged >65 years with acute PE, evaluated in the Emergency Department since 2010 through 2014, were included in this retrospective cohort study. CCI, simplified pulmonary embolism severity index (sPESI) scores and vital status were recorded. Were included 162 patients with confirmed PE, out of 657 suspected cases (24.7%). Median age: 79.2 years, 74.1% presented an sPESI > 1 and 61.1% a CCI > 1. The overall 30, 90-day and 2-year mortality was 11.7% (95%CI 6.6–16.6), 19.8% (95%CI 13.4–25.7) and 31.8% (95%CI 24.1–38.8). For 30-day mortality sPESI showed an AUC 0.642 (95%CI 0.511–0.772) and adding CCI as covariate did not increase its prognostic performance. For 90-day mortality, in an adjusted model including sPESI and CCI, CCI showed a HR 1.282 (95%CI 1.151–1.429, p-value < 0.001), and sPESI a HR = NS(p-value = 0.267). For 2-year mortality, in an adjusted model including sPESI and CCI, CCI showed a HR 1.295 (95%CI 1.180–1.421, p-value < 0.001) and sPESI a HR = NS(p-value = 0.353). In elderly patients with hemodynamically stable PE, the CCI score was found to be an independent predictor of mortality. CCI shows a significantly better ability to predict 90-day and 2-year mortality than sPESI. The assessment of comorbidity burden by using the CCI score may be proposed as an useful tool to predict mortality in these patients.

Background & aims In Caucasian patients with compensated cirrhosis caused by hepatitis B virus (HBV), the risk of hepatocellular carcinoma (HCC) developing persist despite long-term nucleos(t)ide analogs (NUC) treatment. In the surveillance of this population with persistently normal transaminases because of NUCs, the added value of serum alpha-foetoprotein (AFP) monitoring is poorly defined. Methods Two hundred and fifty-eight Caucasian HCC-free patients with HBV-compensated cirrhosis who started tenofovir or entecavir while having normal serum AFP levels (≤7 ng/mL) at baseline or within the first year of treatment underwent HCC surveillance by semiannual ultrasound evaluation and serum AFP determination. Results During 96 (18-120) months of antiviral therapy, 3947 AFP values were collected, median AFP level was 2 ng/mL. Thirty-five patients developed an HCC at an overall 8-year crude cumulative incidence of 14% (annual incidence of 2%). HCC incidence increased in parallel with increasing AFP thresholds: 24%, 36%, 64% and 92% for AFP levels after exceeding 2, 4, 6 and 7 ng/mL for the first-time. Of the 12 patients who experienced an AFP rise > 7 ng/mL, 11 developed an HCC and one had liver metastases of lung cancer. Overall, an AFP > 7 ng/mL had 99.6% specificity, 31.4% sensitivity, 91.7% PPV, 90.2% NPV, LR+ 70.1 and LR- 0.69 for HCC; this excellent specificity was maintained up to 18 months before HCC detection. Conclusions In Caucasian patients with HBV-compensated cirrhosis on long-term NUC, an increase in AFP over 7 ng/mL shows excellent specificity, heralding HCC development within 1 year.

In a general population with acute Pulmonary Embolism (PE) elevated D-dimer concentrations associate with increased mortality. The aim of the study was to assess the ability of D-dimer to predict 30 and 90-days mortality in elderly patients with acute PE. Hemodynamically stable patients aged ≥65 years old with confirmed PE were included in this retrospective cohort study. A pulmonary computerized tomography angiography scan, D-dimer concentrations, simplified Pulmonary Embolism Severity Index (sPESI) variables and vital status were available for all patients. The study included 154 confirmed cases of PE (23.5 % of suspected), median age 79.1 years. D-dimer was higher in patients dead than in those alive at 30 (median 14,547 vs. 8340 ng/mL, p = 0.05) and 90 days (13,604 vs. 7973 ng/mL, p = 0.013). When adding D-dimer to sPESI, the discriminant capacity to predict mortality within 30 and 90 days was increased by 0.080 and 0.089, respectively. The contribution of D-dimer to the discriminating ability was NRI = 0.286 (95 % CI -0.198 to 0.770, p value: 0.247) at 30 days and NRI = 0.605 (95 % CI 0.223-0.988, p-value: 0.002) at 90 days.D-dimer concentration was associated with 30 and 90-days mortality and showed a higher discriminant capacity than sPESI alone to predict 90-days mortality. Adding D-dimer concentrations to sPESI score seems to improve its prognostic ability, supporting multivariable risk models as the best approach to estimate prognosis in elderly patients with PE.

To evaluate the associations between single nucleotide polymorphisms (SNPs) of factors involved in the development of invasive bacterial disease (IBD) in children, 47 SNPs of 18 candidate genes were analysed in 49 children with IBD and 100 controls. The G/T genotype of TLR2 rs2149356 and the C genotype of LTA rs2229094 were associated with significantly reduced risk of developing IBD ( P = 0.04 and P = 0.05, respectively), whereas the C/T genotype of RFP175 rs1585110 was associated with a significantly higher risk of developing IBD ( P = 0.02). These results support the evidence that some genetic variants of factors involved in innate immunity may influence IBD risk in children.

Despite the clear endocrine-metabolic relationship between androgenic activity and adiposity, the role of androgens in breast cancer prognosis according to patient's adiposity is scarcely explored. Here, we aimed at investigating the prognostic value of circulating testosterone in association with patient's body mass index (BMI).Circulating testosterone and BMI were evaluated at breast cancer diagnosis in 460 estrogen receptor (ER)-positive postmenopausal patients. Local relapse, distant metastasi(e)s and contralateral breast cancer were considered recurrence events. The Kruskal-Wallis test was performed to evaluate if testosterone levels differed within subgroups of categorical tumour characteristics. The Cox proportional hazard regression model was fitted to estimate the impact of standard prognostic factors on relapse-specific hazard ratio (HR). After backward selection, a model including continuous testosterone level, BMI categories ( 25, normal-weight; =25-30, overweight; ≥30 kg/mDuring a median follow up of 6.3 years, 45 patients relapsed. Testosterone levels significantly increased across BMI categories (p = 0.001). Both circulating testosterone and BMI were positively associated with disease free survival (p = 0.005 and p = 0.021, respectively). A significant interaction was found between testosterone and BMI (p = 0.006). For normal-weight women, testosterone concentration around median (0.403 ng/mL) or third quartile (0.532 ng/mL) showed a high significant HR of relapse (5.52; 95% CI:1.65-18.49 and 4.55; 95% CI:1.09-18.98, respectively). Overweight patients showed increased HR at increasing testosterone levels, reaching a significant high HR (4.68; 95% CI:1.39-15.70) for testosterone values of 0.782 ng/mL (95th percentile). For obese patients HR decreased (not significantly) at increased testosterone concentrations, explaining the interaction between testosterone levels and BMI categories.In ER-positive postmenopausal breast cancer patients, high testosterone levels are associated with worse prognosis in normal-weight and overweight women, whereas in obese seems to be associated with a better outcome. Although the results require further validation, they suggest that assessment of circulating testosterone and BMI could help to identify postmenopausal ER-positive patients at higher risk of relapse and potentially open new therapeutic strategies.

The objective of this study was to compare survival rate and clinical and radiological outcomes of a cementless mobile-bearing total ankle replacement (TAR) between two groups of patients, affected by end-stage ankle arthritis, with or without a pre-operative varus deformity.A total of 81 patients (81 ankles) were included in the study and divided in two groups. Group A, "varus" group, includes 11 patients with pre-operative varus deformity of more than 10 ° and group B, "neutral" group, includes 70 patients, with a varus/valgus deformity of less than 10 °. American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS), and Short Form (SF)-12 score were used to compare clinical outcomes. Radiological parameters, complications, and survival rate at last follow-up were also recorded.In both groups, all clinical and radiological parameters improved after surgery (p 0.05) without statistically significant difference. Complications were similar between two groups. Overall in three cases, an implant revision was necessary: 1 in group A (9%) at 3.1 years follow-up and 2 (3%) in group B at 3.8 years, without statistically significant difference (p 0.001).Severe varus malalignment should not be considered a contraindication for a mobile-bearing TAR. Nevertheless, TAR in severe deformity should be performed only by experienced surgeons.

Objectives I.v. iloprost (ILO) may be used in the treatment of refractory RP and digital ulcers. We aim to evaluate the acute and chronic effects of two different ILO regimens by power Doppler US (PDUS) and nailfold videocapillaroscopy. Methods In this 3-month single-centre pragmatic non-randomized trial, 96 SSc patients were included and stratified according to ILO treatment as: no ILO (group A), ILO once monthly (group B) and ILO for five consecutive days (group C). Resistivity index (RI), finger pulp blood flow and periungual vascularization by PDUS, and sum of capillaries apex width in 1 mm by nailfold videocapillaroscopy were evaluated. Results were adjusted for the average outdoor temperature at the place of residence. Results An acute ILO effect was observed for only finger pulp blood flow in groups B and C (P < 0.001 and P < 0.005, respectively). An acute effect was observed for RI and periungual vascularization only in group B. A progressive increase was observed for other parameters without statistical difference. ILO effects were not observed any longer before the following infusion. Some parameters (finger pulp blood flow in group B and RI in group C) showed a statistically higher increase the lower the outdoor temperature was. Conclusion ILO had an acute effect as assessed by PDUS, especially in group B. By contrast, an ILO chronic effect was not detectable before the following infusion in both treatment groups. More studies are needed to define how often ILO should be administered.

In patients with Raynaud’s phenomenon (RP), the role of medical history, capillaroscopy, and autoantibodies in order to provide an early diagnosis of connective tissue disease (CTD) were examined. 115 consecutive adults with uni-, bi-, or triphasic colour changes of the fingers were studied. RP was bilateral in 92.7% of patients. The middle finger was significantly more affected. A lack of association between fingers affected by RP and fingers with capillary abnormalities was observedOR=0.75(0.34–1.66). RP with the cyanotic phase had a higher risk at capillaroscopy to have hemorrhagesOR=4.46(1.50–13.30) and giant capillariesOR=24.85(1.48–417.44). The thumb and triphasic involvement have an OR of 1.477 and 1.845, respectively. RP secondary to systemic sclerosis (SSc) had greater value of VAS pain (p=0.011). The presence of anti-centromere antibodies was significantly associated with a higher risk of SSc (p<0.001). 44.3% of subjects had uniphasic blanching of the fingers, and among these, 27% was diagnosed as having an overt or suspected CTD. Markers of a potential development of CTDs include severe RP symptoms, positive autoantibodies, and capillary abnormalities. These data support the proposal to not discharge patients with uniphasic blanching of the fingers to avoid missing the opportunity of an early diagnosis.

Objective To investigate the contribution of serum levels of testosterone (TS) and sex hormone binding globulin (SHBG) in association with body mass index (BMI) as a surrogate marker of obesity, to the predictive capability of tumor size (T), lymph node (N) and estrogen receptor (ER) status and proliferative activity (TLI). Methods We investigated 120 women with primary breast cancer and median follow-up of 138 months. Serum levels of TS and SHBG and patient's BMI were evaluated before surgery. The contribution of TS, SHBG, their ratio (TS/SHBG) and BMI to the predictive capability of tumor-specific biomarkers was investigated by Harrell's c statistic. Results TS alone did not affect prognosis, whereas SHBG was protective in postmenopausal patients, in which BMI was associated with a progressive increase in the relapse-specific hazard ratio (HR). When in combination, TS, SHBG and BMI, affected prognosis in different ways depending on menopausal status. The best predictive capability (c = 0.78) was observed in postmenopausal patients when at the basic model (N + TLI) were added TS, BMI, TS * BMI interaction, with or without SHBG. In premenopause subgroup, the best predictive capability (c = 0.67) was provided by the basic model (N + TLI) plus TS and SHBG or their ratio, BMI and TS * BMI or TS/SHBG * BMI interaction. Conclusions Patient-associated features such as BMI and serum levels of TS and SHBG can improve the predictive capability of consolidate tumor-specific biomarkers in both pre- and postmenopause, thus providing a relevant contribution to the decision-making process.

In 177 children living in an area with high 13-valent pneumococcal conjugate vaccine 13 coverage, who had acute otitis media complicated with spontaneous tympanic membrane perforation, Streptococcus pneumoniae was identified in the middle ear fluid of 48 (27.1%) subjects, with 37 (77.1%) cases caused by nonpneumococcal conjugate vaccine 13 serotypes.

Background Our randomized trial found no survival advantage for axillary dissection (AD) compared observation only (no AD) in older patients with early breast cancer and a clinically negative axilla, indicating that AD is unnecessary. We compared characteristics and outcomes in out-trial patients with those in trial patients to provide indications as to whether AD can be safely omitted outside the trial setting. Methods The trial started in 1996, recruiting 238 patients age 65–80 years with cT1cN0 breast cancer, randomized to conservative surgery with or without AD. Over the recruitment period, 109 eligible patients who refused to participate in the trial, also received conservative breast surgery with or without AD depending on patient preference/surgeon opinion. Trial and out-trial patients received conventionally-fractioned whole breast radiation and tamoxifen for five years. Endpoints were breast cancer mortality, overall survival, and cumulative incidence of axillary disease in patients not receiving AD. Results After 15 years of follow-up, breast cancer mortality and overall survival did not differ between the AD and no AD arms, in either the trial or out-trial cohorts. The 15-year cumulative incidence of axillary relapse was 6% in the no AD arm of the trial group, and zero in the no AD arm of the out-trial group. Conclusions Outside the trial setting, older patients with T1N0 breast cancer can be safely treated by conservative surgery, postoperative radiotherapy and tamoxifen for five years (if ER-positive). Axillary surgery is appropriate only for the small proportion of patients who develop overt axillary disease during follow-up.

To evaluate the aetiological role of the main bacterial pathogens associated with acute otitis media (AOM) in children with AOM and spontaneous tympanic membrane perforation (STMP).Between 1 May 2015 and 30 April 2016, 177 children, aged 6 months to 7 years, with AOM complicated by STMP within 12 h were prospectively enrolled. Middle ear fluid (MEF) was tested by real-time PCR for Streptococcus pneumoniae, non-typeable Haemophilus influenzae, Streptococcus pyogenes, Moraxella catarrhalis and Staphylococcus aureus.Among the 177 children with AOM and STMP, 92/100 (92.0%) of those with recurrent AOM and 13/77 (16.9%) without recurrent AOM had recurrent STMP (p 0.001). A single pathogen was identified in 70 (39.5%) MEF samples, whereas two, three and four bacteria were detected in 54 (30.5%), 20 (11.3%), and 7 (4.0%) cases, respectively. Non-typeable H. influenzae was the most common and was identified in 90 children (50.8%), followed by M. catarrhalis (62 cases, 35.0%) and S. pneumoniae (48 cases, 27.1%). Non-typeable H. influenzae was the most frequent pathogen in children with co-infections. Children with co-infections, including non-typeable H. influenzae, had significantly more frequent recurrent AOM (adjusted OR 6.609, 95% CI 1.243-39.096, p 0.029).Recurrent AOM episodes appear to be associated with an increased risk of AOM with STMP. In AOM with STMP, non-typeable H. influenzae is detected at a high frequency, especially in children with recurrent STMP and often in association with other pathogens.

In order to evaluate the serum anti-skin autoantibodies and cytokine concentrations in patients with different epidermolysis bullosa (EB) types and severity, 42 EB patients and 38 controls were enrolled. Serum anti-skin antibodies were significantly higher in the patients than in the controls (p = 0.008, p < 0.001, p < 0.001, p < 0.001 and p < 0.001 for desmoglein 1 (DSG1) desmoglein 3 (DSG3), bullous pemphigoid 180 (BP180), BP230 and type VII collagen (COL7), respectively). The same trend was observed for interleukin (IL)-1β, IL-2, IL-6, IL-10, tumor necrosis factor-β, and interferon-γ (p < 0.001, p < 0.001, p < 0.001, p = 0.008, p < 0.001 and p = 0.002, respectively). Increases in anti-skin antibodies and cytokine concentrations were higher in patients with recessive dystrophic EB than in those with different types of EB, in generalized cases than in localized ones, and in patients with higher Birmingham Epidermolysis Bullosa Severity (BEBS) scores than in those with a lower score. The BEBS score was directly correlated with BP180, BP230, COL7 (p = 0.015, p = 0.008 and p < 0.001, respectively) and IL-6 (p = 0.03), whereas IL-6 appeared significantly associated with DSG1, DSG3, BP180, BP230 and COL7 (p = 0.015, p = 0.023, p = 0.023, p = 0.015 and p = 0.005, respectively). This study showed that autoimmunity and inflammatory responses are frequently activated in EB, mainly in severe forms, suggesting the use of immunosuppressive drugs or biologicals that are active against pro-inflammatory cytokines to reduce clinical signs and symptoms of disease.

The development of a safe and effective respiratory syncytial virus (RSV) vaccine might be facilitated by knowledge of the natural immune response to this virus. The aims of this study were to evaluate the neutralizing antibody response of a cohort of healthy children

In order to evaluate the adherence of healthcare providers and parents to the current recommendations concerning fever and pain management, randomized samples of 500 healthcare providers caring for children and 500 families were asked to complete an anonymous questionnaire. The 378 health care providers (HCPs) responding to the survey (75.6%) included 144 primary care pediatricians (38.1%), 98 hospital pediatricians (25.9%), 62 pediatric residents (16.4%), and 71 pediatric nurses (19.6%); the 464 responding parents (92.8%) included 175 whose youngest (or only) child was ≤5 years old (37.7%), 175 whose youngest (or only) child was aged 6–10 years (37.7%), and 114 whose youngest (or only) child was aged 11–14 years (24.6%). There were gaps in the knowledge of both healthcare providers and parents. Global adherence to the guidelines was lower among the pediatric nurses than the other healthcare providers (odds ratio 0.875; 95% confidence interval 0.795–0.964). Among the parents, those of children aged 6–10 and 11–14 years old, those who were older, and those without a degree answered the questions correctly significantly less frequently than the others. These findings suggest that there is an urgent need to improve the dissemination of the current recommendations concerning fever and pain management among healthcare providers and parents in order to avoid mistaken and sometimes risky attitudes, common therapeutic errors, and the unnecessary overloading of emergency department resources. Pediatric nurses and parents with older children, those who are older, and those with a lower educational level should be the priority targets of educational programmes.

Evaluation of the genetic contribution to the development of recurrent acute otitis media (rAOM) remains challenging. This study aimed to evaluate the potential association between single nucleotide polymorphisms (SNPs) in selected genes and rAOM and to analyze whether genetic variations might predispose to the development of complicated recurrent cases, such as those with tympanic membrane perforation (TMP). A total of 33 candidate genes and 47 SNPs were genotyped in 200 children with rAOM (116 with a history of TMP) and in 200 healthy controls. INFγ rs 12369470CT was significantly less common in the children with rAOM than in healthy controls (odds ratio [OR] 0.5, 95% confidence interval [CI] 0.25–1, P = 0.04). Although not significant, interleukin (IL)-1β rs 1143627G and toll-like receptor (TLR)-4 rs2737191AG were less frequently detected in the children with rAOM than in controls. The opposite was true for IL-8 rs2227306CT, which was found more frequently in the children with rAOM than in healthy controls. The IL-10 rs1800896TC SNP and the IL-1α rs6746923A and AG SNPs were significantly more and less common, respectively, among children without a history of TMP than among those who suffered from this complication (OR 2.17, 95% CI 1.09–4.41, P = 0.02, and OR 0.42, 95% CI 0.21–0.84, P = 0.01). This study is the first report suggesting an association between variants in genes encoding for factors of innate or adaptive immunity and the occurrence of rAOM with or without TMP, which confirms the role of genetics in conditioning susceptibility to AOM.

The ordinary least squares (OLS) method is routinely used to estimate the unknown concentration of nucleic acids in a given solution by means of calibration. However, when outliers are present it could appear sensible to resort to robust regression methods. We analyzed data from an External Quality Control program concerning quantitative real-time PCR and we found that 24 laboratories out of 40 presented outliers, which occurred most frequently at the lowest concentrations. In this article we investigated and compared the performance of the OLS method, the least absolute deviation (LAD) method, and the biweight MM-estimator in real-time PCR calibration via a Monte Carlo simulation. Outliers were introduced by replacement contamination. When contamination was absent the coverages of OLS and MM-estimator intervals were acceptable and their widths small, whereas LAD intervals had acceptable coverages at the expense of higher widths. In the presence of contamination we observed a trade-off between width and coverage: the OLS performance got worse, the MM-estimator intervals widths remained short (but this was associated with a reduction in coverages), while LAD intervals widths were constantly larger with acceptable coverages at the nominal level.

Raynaud's phenomenon (RP) can be the first manifestation or may be present before the development of an overt systemic sclerosis (SSc).1 Enhanced liver fibrosis (ELF) test, an algorithm combining tissue inhibitors of matrix metalloproteinases (TIMP-1), hyaluronic acid (HA) and aminoterminal propeptide of type III procollagen (PIIINP), has been related to several measures of fibrosis in SSc patients.2–⇓4 We evaluated whether these biomarkers could discriminate between primary and secondary RP. Consecutive adult patients with RP at the first rheumatologic evaluation were recruited from February 2011 to May 2012 with ethics committee approval. Exclusion criteria were history of any fibrosing disorder, organ transplantation, hepatocellular carcinoma or treatment with interferon. One patient was excluded for interferon treatment. Fifteen limited cutaneous SSc and 15 diffuse …
