Invasive aspergillosis in liver transplant recipients: Epidemiology, clinical characteristics, treatment, and outcomes in 116 cases

Invasive aspergillosis (IA) in liver transplant recipients is associated with grave outcomes. We reviewed 116 individual cases reported in the literature from 1985 to 2013. IA was diagnosed after a median of 25 days after transplantation and involved a single organ in 51% of the cases, whereas in the remaining cases, multiple sites were involved. The most common infecting Aspergillus species were Aspergillus fumigatus (73%), Aspergillus flavus (14%), and Aspergillus terreus (8%). Amphotericin B was the drug most frequently used, and it was followed by voriconazole and itraconazole. Combination regimens were used in 51% of the cases. The overall 1‐year cumulative survival probability was 35% [95% confidence interval (CI) = 24.6%‐49.6%]. Survival was significantly higher for patients reported from the year 2000 and thereafter (P < 0.001), for those diagnosed with IA more than 30 days after transplantation versus those diagnosed earlier (P = 0.019), and for patients without renal failure (P = 0.020). Additionally, the use of voriconazole was significantly associated with a higher probability of survival (P < 0.001). Cox regression analysis showed that subjects with the involvement of multiple sites had a 2.52 times higher risk of a negative outcome (95% CI = 1.08‐5.87) than those with the involvement of a single site. Thus, IA causes life‐threatening infections in liver transplant recipients. Predictors associated with poor outcomes may help clinicians to optimize the management of this infection.

Bayesian calibration for forensic age estimation

Forensic medicine is increasingly called upon to assess the age of individuals. Forensic age estimation is mostly required in relation to illegal immigration and identification of bodies or skeletal remains. A variety of age estimation methods are based on dental samples and use of regression models, where the age of an individual is predicted by morphological tooth changes that take place over time. From the medico-legal point of view, regression models, with age as the dependent random variable entail that age tends to be overestimated in the young and underestimated in the old. To overcome this bias, we describe a new full Bayesian calibration method (asymmetric Laplace Bayesian calibration) for forensic age estimation that uses asymmetric Laplace distribution as the probability model. The method was compared with three existing approaches (two Bayesian and a classical method) using simulated data. Although its accuracy was comparable with that of the other methods, the asymmetric Laplace Bayesian calibration appears to be significantly more reliable and robust in case of misspecification of the probability model. The proposed method was also applied to a real dataset of values of the pulp chamber of the right lower premolar measured on x-ray scans of individuals of known age.

The effect of the macrobiotic Ma-Pi 2 diet vs. the recommended diet in the management of type 2 diabetes: the randomized controlled MADIAB trial

BackgroundDiet is an important component of type 2 diabetes therapy. Low adherence to current therapeutic diets points out to the need for alternative dietary approaches. This study evaluated the effect of a different dietary approach, the macrobiotic Ma-Pi 2 diet, and compared it with standard diets recommended for patients with type 2 diabetes.MethodsA randomized, controlled, open-label, 21-day trial was undertaken in patients with type 2 diabetes comparing the Ma-Pi 2 diet with standard (control) diet recommended by professional societies for treatment of type 2 diabetes. Changes in fasting blood glucose (FBG) and post-prandial blood glucose (PPBG) were primary outcomes. HbA1c, insulin resistance (IR), lipid panel and anthropometrics were secondary outcomes.ResultsAfter correcting for age, gender, BMI at baseline, and physical activity, there was a significantly greater reduction in the primary outcomes FBG (95% CI: 1.79; 13.46) and PPBG (95% CI: 5.39; 31.44) in those patients receiving the Ma-Pi 2 diet compared with those receiving the control diet. Statistically significantly greater reductions in the secondary outcomes, HbA1c (95% CI: 1.28; 5.46), insulin resistance, total cholesterol, LDL cholesterol and LDL/HDL ratio, BMI, body weight, waist and hip circumference were also found in the Ma-Pi 2 diet group compared with the control diet group. The latter group had a significantly greater reduction of triglycerides compared with the Ma-Pi 2 diet group.ConclusionsIntervention with a short-term Ma-Pi 2 diet resulted in significantly greater improvements in metabolic control in patients with type 2 diabetes compared with intervention with standard diets recommended for these patients.Trial registrationCurrent Controlled Trials ISRCTN10467793.

Sclerostin and Antisclerostin Antibody Serum Levels Predict the Presence of Axial Spondyloarthritis in Patients with Inflammatory Bowel Disease

Objective. The early diagnosis of inflammatory bowel disease (IBD)-associated spondyloarthritis (SpA/IBD) in patients affected by IBD represents a major topic in clinical practice; in particular, to date there are no available serum biomarkers revealing the presence of joint inflammation in these patients. Sclerostin (SOST), an antagonist of the Wnt/β-catenin pathway, and antisclerostin-immunoglobulin G (anti-SOST–IgG) have been recently studied in patients with ankylosing spondylitis (AS) as a putative marker of disease activity. Methods. SOST and anti-SOST-IgG serum levels were assayed in 125 patients with IBD, 85 with axial or peripheral SpA, and in control groups (patients with AS and rheumatoid arthritis, and healthy individuals). The diagnostic performance in discriminating the presence of SpA/IBD was assessed for both candidate biomarkers. Results. Patients affected by SpA/IBD with axial involvement displayed significantly lower levels of SOST and higher levels of anti-SOST-IgG compared to patients with only peripheral arthritis, IBD, and controls. Moreover, SOST and anti-SOST-IgG serum levels were inversely correlated and were associated with the duration of articular symptoms. Both biomarkers showed good accuracy in predicting the presence of axial SpA in patients with IBD. Conclusion. We demonstrated that in patients with IBD, SOST and anti-SOST-IgG might represent novel biomarkers to assess the presence of axial joint involvement. Moreover, the development of anti-SOST-IgG and the subsequent decrease of SOST serum levels could play a role in the pathogenesis of SpA/IBD.

High frequency of diabetic ketoacidosis at diagnosis of type 1 diabetes in Italian children: a nationwide longitudinal study, 2004–2013

This longitudinal population-based study analyses the frequency of diabetic ketoacidosis (DKA) at type 1 diabetes diagnosis in Italian children under 15 years of age, during 2004–2013. DKA was defined as absent (pH ≥ 7.30), mild/moderate (7.1 ≤ pH < 7.30) and severe (pH < 7.1). Two multiple logistic regression models were used to evaluate the time trend of DKA frequency considered as present versus absent and severe versus absent, adjusted for gender, age group and geographical area of residence at diagnosis. Overall, 9,040 cases were ascertained. DKA frequency was 40.3% (95%CI: 39.3–41.4%), with 29.1% and 11.2% for mild/moderate and severe DKA, respectively. Severe DKA increased significantly during the period (OR = 1.03, 95%CI: 1.003–1.05). Younger-age children and children living in Southern Italy compared to Central Italy were at significantly higher risk of DKA and severe DKA. Family history of type 1 diabetes and residence in Sardinia compared to Central Italy were significantly associated with a lower probability of DKA and severe DKA. The high frequency of ketoacidosis in Italy over time and high variability among age groups and geographical area of residence, strongly suggests a continuing need for nationwide healthcare strategies to increase awareness of early detection of diabetes.

STANDARD CUT RATE 25-GAUGE VITRECTOMY VERSUS ULTRAHIGH-SPEED 25-GAUGE SYSTEM IN CORE VITRECTOMY: A Randomized Clinical Trial.

Purpose: The aim of this study was to compare the efficiency and safety of ultrahigh-speed cut rate 25-gauge system and standard cut rate 25-gauge vitrectomy system. Methods: In this single-center, prospective randomized study, all consecutive eyes that underwent 25-gauge vitrectomy at the Eye Clinic of the University of Ancona from September 2014 to November 2014 were randomized to receive 25-gauge vitrectomy with 7,500 cuts per minute (cpm) probes (7,500 Group) or 25-gauge vitrectomy with 5,000 cpm probes (Standard Group). Exclusion criteria were previously vitrectomized eye, trauma cases, retinal detachment with proliferative vitreoretinopathy, and endophthalmitis. Main outcome measure was core vitrectomy duration. Secondary outcome was the incidence of iatrogenic retinal breaks and other complications related to surgery. Results: Overall, 62 eyes were enrolled; 31 eyes received 25-gauge 7,500 cpm vitrectomy and 31 eyes received 25-gauge 5,000 cpm vitrectomy. The duration of core vitrectomy was significantly lower in the 7,500 Group (P = 0.030, t-test for independent samples). Mean ± standard deviation core vitrectomy time was 161.32 ± 39.10 seconds in the 7,500 Group and 184.10 ± 41.69 seconds in the Standard Group. The observed difference in mean core vitrectomy duration between subjects treated with 7,500 cpm probes and those in the Standard Group was equal −22 seconds (95% confidence interval: −43.3 to −2.2). There was no difference in the incidence of iatrogenic breaks between the 2 groups, and there were no other complications over a 3-month follow-up period. Conclusion: The 25-gauge 7,500 cpm vitrectomy is an effective and safe surgical procedure, and it can significantly reduce core vitrectomy time in eyes undergoing vitreoretinal surgery.

Effect of a barley-vegetable soup on plasma carotenoids and biomarkers of cardiovascular disease

Functional foods that provide benefits beyond their traditional nutritional value have attracted much interest. Aim of the study was to evaluate the nutritional and the functional properties of a frozen ready-to-eat soup containing barley and pigmented vegetables. Both glycaemic index and the glyceamic load of ready-to-eat soup were evaluated in vivo. Moreover the bioavailability of carotenoids (lutein and beta-carotene) and the effect on lipid profile and lipid peroxidation were studied in 38 volunteers whose diet was supplemented for two weeks with a daily portion (250 g) of the ready-to-eat soup. Plasma levels of carotenoids (lutein and beta-carotene) and plasma total antioxidant capacity significantly increased after 2 weeks of treatment. Furthermore, we observed a decrease in the levels of lipids (total cholesterol and low density lipoprotein-cholesterol) and of markers of lipid peroxidation (oxidized low density lipoprotein and lipid hydroperoxides) in plasma of all subjects. The glyceamic index of the product was 36, therefore it could be considered a low glyceamic index food. An accurate selection of vegetable foods results in a palatable and healthy product that provides benefits on plasma lipids and lipid peroxidation (Protocol number 211525).

Effectiveness of adherence to recommended clinical examinations of diabetic patients in preventing diabetes-related hospitalizations

Objective To validate a set of indicators for quality of diabetes care through their relationship with measurable clinical outcomes. Design A retrospective cohort study was carried out from 2010 to 2015. Setting Population-based study. Data were retrieved from healthcare utilization databases of three Italian regions (Lombardy, Emilia Romagna and Lazio) on the whole covering 20 million citizens. Participants The 77 285 individuals who were newly taken in care for diabetes during 2010 entered into the cohort. Interventions Exposure to selected clinical recommendations (i.e. periodic controls for glycated hemoglobin, lipid profile, urine albumin excretion, serum creatinine and dilated eye exams) was recorded. Main outcomes measures A composite outcome was employed taking into account hospitalizations for brief-term diabetes complications, uncontrolled diabetes, long-term vascular outcomes and no traumatic lower limb amputation. A multivariable proportional hazards model was fitted to estimate hazard ratio, and 95% confidence intervals (CI), for the exposure-outcome association. Results Among the newly taken in care patients with diabetes, those who adhered to almost none (0 or 1), just some (2 or 3) or almost all (4 or 5) recommendations during the first year after diagnosis were 44%, 36% and 20%, respectively. Compared patients who adhered to almost none recommendation, significant risk reductions of 16% (95% CI, 6-24%) and 20% (7-28%) were observed for those who adhered to just some and almost all recommendations, respectively. Conclusions Tight control of patients with diabetes through regular clinical examinations must to be considered the cornerstone of national guidance, national audits and quality improvement incentives schemes.

A 6-month follow-up study of the randomized controlled Ma-Pi macrobiotic dietary intervention (MADIAB trial) in type 2 diabetes

Background:In the MADIAB trial (a 21-day randomized, controlled trial in patients with type 2 diabetes (T2D)), intervention with the Ma-Pi 2 macrobiotic diet resulted in significantly greater improvements in metabolic control compared with a standard recommended diet for patients with T2D. We report on a 6-month follow-up study, which investigated, whether these benefits extended beyond the 21-day intensive dietary intervention, in real-world conditions.Subjects:At the end of the MADIAB trial (baseline of this follow-up study), all participants continued their assigned diet (Ma-Pi or control) for 6 months. The Ma-Pi 2 group followed the Ma-Pi 4 diet during this follow-up study. Forty of the original 51 subjects (78.4%) participated in the follow-up (body mass index, 27–45 kg m−2; age, 40–75 years). Primary outcome was percentage change from baseline in HbA1c; secondary outcomes were anthropometric data and lipid panel.Results:A significantly greater median percentage reduction was observed for HbA1c in the Ma-Pi group (−11.27% (95% confidence interval (CI): −10.17; −12.36)) compared with the control group (−5.88% (95% CI: −3.79; −7.98)) (P < 0.001). Total and low-density lipoprotein (LDL) cholesterol increased in both groups with no differences between groups (P=0.331 and P=0.082, respectively). After correcting for age and gender, the Ma-Pi diet was associated with a higher percentage reduction in HbA1c (95% CI: 2.56; 7.61) and body weight (95% CI: 0.40; 3.99), and a higher percentage increase in LDL cholesterol (95% CI: −1.52; −33.16). However, all participants’ total and LDL cholesterol levels remained within recommended ranges (<200 mg dl−1 and <100 mg dl−1, respectively). The Ma-Pi diet group achieved the target median HbA1c value (<5.7% (39 mmol mol−1)) at 6 months.Conclusions:Both the Ma-Pi and control diets maintained their benefits beyond the 21-day intensive monitored intervention over a 6-month follow-up in real-world conditions. The Ma-Pi diet resulted in greater improvement in glycemic control.
