RESUMEN

Prognostic assessment of patients with hepatocellular carcinoma (HCC) at the time of diagnosis remains controversial and becomes even more complex at the time of restaging when new variables need to be considered. The aim of the current study was to evaluate the prognostic utility of restaging patients before proceeding with additional therapies for HCC. Two independent Italian prospective databases were used to identify 1,196 (training cohort) and 648 (validation cohort) consecutive patients with HCC treated over the same study period (2008-2015) who had complete restaging before decisions about additional therapies. The performance of the Italian Liver Cancer (ITA.LI.CA) prognostic score at restaging was compared with that of the Barcelona Clinic Liver Cancer, Hong Kong Liver Cancer, and Cancer of the Liver Italian Program systems. A multivariable Cox survival analysis was performed to identify baseline, restaging, or dynamic variables that were able to improve the predictive performance of the prognostic systems. At restaging, 35.3% of patients maintained stable disease; most patients were either down-staged by treatment (27.2%) or had disease progression (37.5%). The ITA.LI.CA scoring system at restaging demonstrated the best prognostic performance in both the training and validation cohorts (c-index 0.707 and 0.722, respectively) among all systems examined. On multivariable analysis, several variables improved the prognostic ability of the ITA.LI.CA score at restaging, including progressive disease after the first treatment, Model for End-Stage Liver Disease at restaging, and choice of nonsurgical treatment as additional therapy. A new ITA.LI.CA restaging model was created that demonstrated high discriminative power in both the training and validation cohorts (c-index 0.753 and 0.745, respectively). CONCLUSION: Although the ITA.LI.CA score demonstrated the best prognostic performance at restaging, other variables should be considered to improve the prognostic assessment of patients at the time of deciding additional therapies for HCC.

RESUMEN

BACKGROUND: Italian pediatric antimicrobial prescription rates are among the highest in Europe. As a first step in an Antimicrobial Stewardship Program, we implemented a Clinical Pathway (CP) for Community Acquired Pneumonia with the aim of decreasing overall prescription of antibiotics, especially broad-spectrum. MATERIALS AND METHODS: The CP was implemented on 10/01/2015. We collected antibiotic prescribing and outcomes data from children aged 3 months-15 years diagnosed with CAP from 10/15/2014 to 04/15/2015 (pre-intervention period) and from 10/15/2015 to 04/15/2016 (post-intervention period). We assessed antibiotic prescription differences pre- and post-CP, including rates, breadth of spectrum, and duration of therapy. We also compared length of hospital stay for inpatients and treatment failure for inpatients and outpatients. Chi-square and Fisher's exact test were used to compare categorical variables and Wilcoxon rank sum test was used to compare quantitative outcomes. RESULTS: 120 pre- and 86 post-intervention clinic visits were identified with a diagnosis of CAP. In outpatients, we observed a decrease in broad-spectrum regimens (50% pre-CP vs. 26.8% post-CP, p = 0.02), in particular macrolides, and an increase in narrow-spectrum (amoxicillin) post-CP. Post-CP children received fewer antibiotic courses (median DOT from 10 pre-CP to 8 post-CP, p<0.0001) for fewer days (median LOT from 10 pre-CP to 8 post-CP, p<0.0001) than their pre-CP counterparts. Physicians prescribed narrow-spectrum monotherapy more frequently than broad-spectrum combination therapy (DOT/LOT ratio 1.157 pre-CP vs. 1.065 post-CP). No difference in treatment failure was reported before and after implementation (2.3% pre-CP vs. 11.8% post-CP, p = 0.29). Among inpatients we also noted a decrease in broad-spectrum regimens (100% pre-CP vs. 66.7% post-CP, p = 0.02) and the introduction of narrow-spectrum regimens (0% pre-CP vs. 33.3% post-CP, p = 0.02) post-CP. Hospitalized patients received fewer antibiotic courses post-CP (median DOT from 18.5 pre-CP to 10 post-CP, p = 0.004), while there was no statistical difference in length of therapy (median LOT from 11 pre-CP to 10 post-CP, p = 0.06). Days of broad spectrum therapy were notably lower post-CP (median bsDOT from 17 pre-CP to 4.5 post-CP, p <0.0001). No difference in treatment failure was reported before and after CP implementation (16.7% pre-CP vs. 15.4% post-CP, p = 1). CONCLUSIONS: Introduction of a CP for CAP in a Pediatric Emergency Department led to reduction of broad-spectrum antibiotic prescriptions, of combination therapy and of duration of treatment both for outpatients and inpatients.

RESUMEN

Osteoarthritis (OA) is the most common form of arthritis clinically characterized by joint pain, functional limitation, and reduced quality of life. Several studies have shown a clear link between obesity and higher risk of knee OA. According to the multifactorial OA pathogenesis, the management of this condition requires a multidisciplinary approach. The objective of this study is to evaluate hydrokinesitherapy effects in thermal setting in obese patients with knee OA. Fifty-three patients were assessed for eligibility, of which 33 refused the treatment, while 10 patients dropped out after the enrollment for personal reasons or inability to adhere to the program. Ten patients (8 females, 2 males, mean age of 59.4 years) with obesity (range BMI 30-45 kg/m2) and knee OA (II-III grade of Kellgren-Lawrence scale) treated with hydrokinetic therapy in thermal water (two sessions per week for 8 consecutive weeks) completed the study. Primary outcome measure was pain (VAS). Secondary outcomes were clinical knee evaluation (range of motion-ROM, lower-limb muscle strength), WOMAC, and Lequesne Algofunctional Index. Patellar tendon and peri-articular soft tissue ultrasound evaluation and gait analysis at baseline (T0), at the end of treatment (T1), and at 6 months of follow-up (T2) were performed. Significant decrease on VAS pain during walking on a flat surface and going up/down stairs was reached from baseline at T1 (p = 0.0039; p = 0.0098) and was maintained at T2 (p = 0.00954) exclusively for VAS pain during walking on a flat surface. WOMAC score showed a significant reduction between T0 and T1 (p = 0.0137) and between T0 and T2 (p = 0.006438), as ROM evaluations. Kinematic path assessment did not show significant results in individual gait steps, except for the space-time variables of the average speed and the values of ground reaction force (GRF) obtained with force platforms. Hydrokinesitherapy in thermal environment in obese patients with knee OA may determine pain relief, joint function improvement, and walking speed increase until 6 months of follow-up.

RESUMEN

PURPOSE: to assess bone damage and metabolic abnormalities in patients with Addison's disease given replacement doses of glucocorticoids and mineralocorticoids. METHODS: A total of 87 patients and 81 age-matched and sex-matched healthy controls were studied. The following parameters were measured: urinary cortisol, serum calcium, phosphorus, creatinine, 24-h urinary calcium excretion, bone alkaline phosphatase, parathyroid hormone, serum CrossLaps, 25 hydroxyvitamin D, and 1,25 dihydroxyvitamin D. Clear vertebral images were obtained with dual-energy X-ray absorptiometry in 61 Addison's disease patients and 47 controls and assessed using Genant's classification. RESULTS: Nineteen Addison's disease patients (31.1%) had at least one morphometric vertebral fracture, as opposed to six controls (12.8%, odds ratio 3.09, 95% confidence interval 1.12-8.52). There were no significant differences in bone mineral density parameters at any site between patients and controls. In Addison's disease patients, there was a positive correlation between urinary cortisol and urinary calcium excretion. Patients with fractures had a longer history of disease than those without fractures. Patients taking fludrocortisone had a higher bone mineral density than untreated patients at all sites except the lumbar spine. CONCLUSIONS: Addison's disease patients have more fragile bones irrespective of any decrease in bone mineral density. Supra-physiological doses of glucocorticoids and longer-standing disease (with a consequently higher glucocorticoid intake) might be the main causes behind patients' increased bone fragility. Associated mineralocorticoid treatment seems to have a protective effect on bone mineral density.

RESUMEN

Treatment options are insufficient in patients with adrenocortical carcinoma (ACC). Based on the efficacy of sorafenib, a tyrosine kinase inhibitor, and everolimus, an inhibitor of the mammalian target of rapamycin in tumors of different histotype, we aimed at testing these drugs in adrenocortical cancer models. The expression of vascular endothelial growth factor and its receptors (VEGFR1-2) was studied in 18 ACCs, 33 aldosterone-producing adenomas, 12 cortisol-producing adenomas, and six normal adrenal cortex by real-time PCR and immunohistochemistry and by immunoblotting in SW13 and H295R cancer cell lines. The effects of sorafenib and everolimus, alone or in combination, were tested on primary adrenocortical cultures and SW13 and H295R cells by evaluating cell viability and apoptosis in vitro and tumor growth inhibition of tumor cell line xenografts in immunodeficient mice in vivo. VEGF and VEGFR1-2 were detected in all samples and appeared over-expressed in two-thirds of ACC specimens. Dose-dependent inhibition of cell viability was observed particularly in SW13 cells after 24 h treatment with either drug; drug combination produced markedly synergistic growth inhibition. Increasing apoptosis was observed in tumor cells treated with the drugs, particularly with sorafenib. Finally, a significant mass reduction and increased survival were observed in SW13 xenograft model undergoing treatment with the drugs in combination. Our data suggest that an autocrine VEGF loop may exist within ACC. Furthermore, a combination of molecularly targeted agents may have both antiangiogenic and direct antitumor effects and thus could represent a new therapeutic tool for the treatment of ACC.

RESUMEN

AIM: A total of 371 patients under stable warfarin therapy were retrospectively selected to develop a pharmacogenetic algorithm to identify the individual maintenance dose. MATERIALS & METHODS: The variables that were entered into the algorithm were: VKORC1, CYP2C9 and CYP4F2 polymorphisms, body surface area and age. RESULTS: The percentage of cases whose predicted mean weekly warfarin dose was within 20% of the actual maintenance dose was 51.8% considering patients overall, and were 36.2, 66.2 and 55.4%, respectively, taking into account patients requiring low (≤25 mg/week), intermediate (25-45 mg/week) and high (≥45 mg/week) doses. The algorithm could correctly assign 73.8 and 63.2% of patients to the low- and high-dose regimens, respectively. We developed and validated a pharmacogenetic algorithm in a series of Italian patients, we then tested, in the same series of italian patients, the formulas of three published algorithms. These three algorithms were developed and validated by their authors in a series of patients different from our own. The performance of our algorithm in our patients series was slightly higher than that achieved when using the three other algorithms in our patients series. CONCLUSION: The high predictive accuracy of low and high warfarin requirements of our algorithm warrants its application in prospective studies for clinical validation.

RESUMEN

The aim of this study was to compare nifedipine and carvedilol in the treatment of de novo arterial hypertension after orthotopic liver transplantation (OLT). The study included 50 patients who developed arterial hypertension after OLT. Twenty-five patients received nifedipine (group A), and 25 received carvedilol (group B). Patients were defined as intolerant to nifedipine or carvedilol if severe adverse effects developed. These patients stopped the first drug and were switched to the other one. Patients were defined as full responders to monotherapy if there was normalization of blood pressure, and they were defined as partial responders by the need to add a second antihypertensive drug, ramipril. The 2 groups of patients were similar for baseline conditions. At the end of the study, patients intolerant to monotherapy were 48% of group A and 12.5% of group B (P < 0.01). Full responders were 20% of group A and 33.33% of group B (P < 0.01). Partial responders were 22% of group A and 54.1% of group B (P < 0.01). The addition of ramipril normalized blood pressure in 19% of partial responders to monotherapy (75% in partial responders to nifedipine and 30% in partial responders to carvedilol, P < 0.01). In responders to either monotherapy or combined therapy, there was a significant improvement of renal function. In responders to carvedilol, but not in responders to nifedipine, the daily dose of tacrolimus at 1 year should be reduced to 50% compared to the baseline dose to maintain the blood trough level in the therapeutic range.
