Wrist Ultrasound Analysis Of Patients With Early Rheumatoid Arthritis.

In the present study, we evaluated 42 wrists using the semi-quantitative scales power Doppler ultrasound (PDUS) and gray scale ultrasound (GSUS) with scores ranging from 0 to 3 and correlated the results with clinical, laboratory and radiographic data. Twenty-one patients (17 women and 4 men) with rheumatoid arthritis according to criteria of the American College of Rheumatology were enrolled in the study from September 2008 to July 2009 at Universidade Estadual de Campinas (UNICAMP). The average disease duration was 14 months. The patients were 66.6% Caucasians and 33.3% non-Caucasians, with a mean age of 42 and 41 years, respectively. A dorsal longitudinal scan was performed by ultrasound on the radiocarpal and midcarpal joints using GE LOGIQ XP-linear ultrasound and a high frequency (8-10 MHz) transducer. All patients were X-rayed, and the Larsen score was determined for the joints, with grades ranging from 0 to V. This study showed significant correlations between clinical, sonographic and laboratory data: GSUS and swollen right wrist (r = 0.546), GSUS of right wrist and swelling of left wrist (r = 0.511), PDUS of right wrist and pain in left wrist (r = 0.436), PDUS of right wrist and C-reactive protein (r = 0.466). Ultrasound can be considered a useful tool in the diagnosis of synovitis in early rheumatoid arthritis mainly when the anti-cyclic citrullinated peptide and rheumatoid factor are negative, and can lead to an early change in the therapeutic decision.4411-

Combination of ozone and activated carbon for Pharmaceuticals and Personal Care Products (PPCPs) removal in drinking water: influence of compounds characteristics and organic matter competition

The presence of Pharmaceuticals and Personal Care Products (PPCPs) in drinking water is raising concern for potential negative effects on human health. Ozonation and adsorption on activated carbon (AC) are the most promising processes for PPCPs removal among those usually present in drinking water treatment plants (DWTPs). To evaluate the performance of these processes, both individually and in combination, adsorption isotherms were determined on real matrices collected in a DWTP before and after ozonation, focusing on 10 PPCPs identified as the most critical for the analysed DWTP. AC showed higher PPCPs removals than ozonation, but the combination of the two processes was beneficial. However, the effect of ozone on adsorption depends on PPCPs reactivity with ozone. A competitive effect of organic matter on PPCPs adsorption was observed. Finally, the removal of absorbance at 254 nm is a good proxy variable for PPCPs removal

Fate of Pharmaceuticals and Personal Care Products (PPCPs) from discharge to drinking water: a modelling and monitoring integrated framework

Pharmaceuticals and Personal Care Products (PPCPs) presence in drinking water is gaining growing concern for potential negative effects on human health. This study combined modelling of river transport with monitoring campaigns performed over one year at a drinking water treatment plant (DWTP) located at the closure section of Po river basin, to evaluate the types of released PPCPs, their concentrations and fate in both the river and the DWTP. Over the 114 monitored PPCPs, maximum 23 compounds have been detected at the DWTP inlet with concentrations from 10 to 1800 ng/L, varying among PPCPs and in time. The transport in Po river of iopamidol, with the highest concentration at the DWTP inlet, was simulated combining hydrological and quality data and models. Finally, DWTP monitoring showed that ozonation and adsorption onto activated carbon have the main impact in reducing a wide variety of PPCPs, with performances influenced by their characteristics

A Prospective, Multicenter Evaluation of Predictive Factors for Positive Surgical Marg insAfter Nephron-Sparing Surgery for Renal Cell Carcinoma: The RECORd1 Italian Project.

The purpose of this study was to evaluate the predictors of positive margins in one of the largest available prospective multi-institutional studies. PATIENTS AND METHODS: We evaluated all patients who underwent NSS for radiologically diagnosed kidney tumors between January 2009 and December 2012 at 19 urological Italian centers (Registry of Conservative Renal Surgery [RECORd] project). Preoperative and anthropometric data, comorbidities, intraoperative and postoperative outcomes, and histological findings were analyzed. The negative and PSMs were compared according to the clinical and surgical variables. Multivariable logistic regression models were applied to analyze predictors of PSMs. RESULTS: Eight hundred consecutive patients were evaluated. Seven hundred sixty-one (95.1%) and 39 patients (4.9%) achieved negative and PSMs, respectively. Patients with PSMs were significantly older compared with those with negative margins (median age: 66.6 vs. 61.8 years, respectively; P = .001). A higher incidence of PSMs was observed when NSS was performed for renal masses located in the upper pole (P = .001). A lower rate of PSMs was found in patients treated with simple enucleation rather than standard PN (1.6% vs. 7.4%, respectively; P < .0001). A greater incidence of PSMs was found in Fuhrman 3/4 tumors (11.3%; P < .0001). At multivariable analysis, age (odds ratio [OR], 1.04; P = .01), upper pole tumor location (OR, 2.85; P = .005), standard PN (OR, 3.45; P = .004), and Fuhrman 3-4 nuclear grade (OR, 4.81; P = .001) were found to be independent predictors of PSMs. CONCLUSION: In our multi-institutional report, young age, simple enucleation, middle or lower tumor location, and low-grade tumor were demonstrated to be independent predictors of negative SMs

A snapshot of nephron-sparing surgery in Italy: A prospective, multicenter report on clinical and perioperative outcomes (the RECORd 1 project).

INTRODUCTION: Nephron-sparing surgery (NSS) has become the standard of care for the surgical management of small and clinically localized renal cell carcinoma (RCC). The conservative management of those RCCs is increasing over time. Aim of this study was to report a snapshot of the clinical, perioperative and oncological results after NSS for RCC in Italy. MATERIAL AND METHODS: We evaluated all patients who underwent conservative surgical treatment for renal tumours between January 2009 and December 2012 at 19 urological Italian Centers (RECORd project). Perioperative, radiological and histopathological data were recorded. Surgical eras (2009 vs 2012 and year periods 2009-2010 vs 2011-2012) were compared. RESULTS: Globally, 983 patients were evaluated. More recently, patients undergoing NSS were found to be significantly younger (p = 0.05) than those surgically treated in the first study period, with a significantly higher rate of NSS with relative and imperative indication (p < 0.001). More recently, a higher percentage of procedures for cT1b or cT2 renal tumours was observed (p = 0.02). Utilization rate of open partial nephrectomy (OPN) constantly decreased during years, laparoscopic partial nephrectomy (LPN) remained almost constant while robot-assisted partial nephrectomy (RAPN) increased. The rate of clampless NSS constantly increased over time. The use of at least one haemostatic agent has been significantly more adopted in the most recent surgical era (p < 0.001). CONCLUSIONS: The utilization rate of NSS in Italy is increasing, even in elective and more complex cases. RAPN has been progressively adopted, as well as the intraoperative utilization of haemostatic agents and the rate of clampless procedures

Evaluation of cell proliferation and apoptosis markers as predictive factors for electrochemotherapy in cutaneous squamous cell carcinoma of cats

ABSTRACT: Determining cell proliferation rates and tumor apoptosis through immunohistochemistry allows the evaluation of the biological behavior of the tumor, optimizing the patient’s clinical course. This study aimed to analyze the immunohistochemical expression of Ki-67, COX-2 and caspase-3 and correlate them with the type of response to ECT in feline cutaneous squamous cell carcinoma (SCC), thus determining the predictive potential of these variables. For this, 13 samples of feline cutaneous SCC were evaluated before ECT, and statistical analyses of the correlation intensity between the variables were performed using the Spearman correlation coefficient, with a significance level of 95%. The results indicate a significant negative correlation between histopathological grade and response to ECT (ρ=-0.6; p=0.03); there was no significant correlation between Ki-67, COX-2 and caspase-3 immunoexpression with the response to ECT (ρ=-0.18; p=0.54/ρ=-0.23; p=0.44/ρ=-0.12; p=0.69, respectively). Therefore, the study shows that the histopathological grade, tumor size and staging, degree of cellular pleomorphism and degree of inflammatory infiltrate can be considered negative prognostic factors for cutaneous SCC and negative predictors for response to ECT. However, the markers Ki-67, COX-2 and caspase-3 are not considered predictive factors for the type of response to ECT. In addition, no relationship between these immunoexpressions and greater tumor aggressiveness was observed. The SCCs evaluated in this study showed significant COX-2 labeling, indicating a potential therapeutic target. ECT has been shown to be safe and effective for local control of feline cutaneous SCC but with reduced effectiveness in larger and invasive lesions

Developmental language disorder: Early predictors, age for the diagnosis, and diagnostic tools. A scoping review

Background. Developmental Language Disorder (DLD) is frequent in childhood and may have long-term sequelae. By employing an evidence-based approach, this scoping review aims at identifying (a) early predictors of DLD; (b) the optimal age range for the use of screening and diagnostic tools; (c) effective diagnostic tools in preschool children. Methods. We considered systematic reviews, meta-analyses, and primary observational studies with control groups on predictive, sensitivity and specificity values of screening and diagnostic tools and psycholinguistic measures for the assessment of DLD in preschool children. We identified 37 studies, consisting of 10 systematic reviews and 27 primary studies. Results. Delay in gesture production, receptive and/or expressive vocabulary, syntactic comprehension, or word combination up to 30 months emerged as early predictors of DLD, a family history of DLD appeared to be a major risk factor, and low socioeconomic status and environmental input were reported as risk factors with lower predictive power. Optimal time for screening is suggested between age 2 and 3, for diagnosis around age 4. Because of the high variability of sensitivity and specificity values, joint use of standardized and psycholinguistic measures is suggested to increase diagnostic accuracy. Conclusions. Monitoring risk situations and employing caregivers\u2019 reports, clinical assessment and multiple linguistic measures are fundamental for an early identification of DLD and timely interventions
