Economic evaluations of radioembolization with Itrium-90 microspheres in hepatocellular carcinoma: a systematic review

Background

Transarterial radioembolization (TARE) with yttrium-90 microspheres is a clinically effective therapy for hepatocellular carcinoma (HCC) treatment. This study aimed to perform a systematic review of the available economic evaluations of TARE for the treatment of HCC.

Methods

The Preferred Reported Items for Systematic reviews and Meta-Analyses guidelines was followed by applying a search strategy across six databases. All studies identified as economic evaluations with TARE for HCC treatment in English or Spanish language were considered. Costs were adjusted using the 2020 US dollars based on purchasing-power-parity ($US PPP).

Results

Among 423 records screened, 20 studies (6 cost-analyses, 3 budget-impact-analyses, 2 cost-effectiveness-analyses, 8 cost-utility-analyses, and 1 cost-minimization analysis) met the pre-defined criteria for inclusion. Thirteen studies were published from the European perspective, six from the United States, and one from the Canadian perspectives. The assessed populations included early- (n = 4), and intermediate-advanced-stages patients (n = 15). Included studies were evaluated from a payer perspective (n = 20) and included both payer and social perspective (n = 2). TARE was compared with transarterial chemoembolization (TACE) in nine studies or sorafenib (n = 11). The life-years gained (LYG) differed by comparator: TARE versus TACE (range: 1.3 to 3.1), and TARE versus sorafenib (range: 1.1 to 2.53). Of the 20 studies, TARE was associated with lower treatment costs in ten studies. The cost of TARE treatment varied widely according to Barcelona Clinic Liver Cancer (BCLC) staging system and ranged from 1311 $US PPP/month (BCLC-A) to 71,890 $US PPP/5-years time horizon (BCLC-C). The incremental cost-utility ratio for TARE versus TACE resulted in a 17,397 $US PPP/Quality-adjusted-Life-Years (QALY), and for TARE versus sorafenib ranged from dominant (more effectiveness and lower cost) to 3363 $US PPP/QALY.

Conclusions

Economic evaluations of TARE for HCC treatment are heterogeneous. Overall, TARE is a cost-effective short- and long-term therapy for the treatment of intermediate-advanced HCC.

Case Report: Differential Genomics and Evolution of a Meningeal Melanoma Treated With Ipilimumab and Nivolumab

Primary melanocytic tumors of the CNS are extremely rare conditions, encompassing different disease processes including meningeal melanoma and meningeal melanocytosis. Its incidence range between 3-5%, with approximately 0.005 cases per 100,000 people. Tumor biological behavior is commonly aggressive, with poor prognosis and very low survivability, and a high recurrence rate, even after disease remission with multimodal treatments. Specific genetic alterations involving gene transcription, alternative splicing, RNA translation, and cell proliferation are usually seen, affecting genes like BRAF, TERT, GNAQ, SF3B1, and EIF1AX. Here we present an interesting case of a 59-year-old male presenting with neurologic symptoms and a further confirmed diagnosis of primary meningeal melanoma. Multiple therapy lines were used, including radiosurgery, immunotherapy, and chemotherapy. The patient developed two relapses and an evolving genetic makeup that confirmed the disease’s clonal origin. We also provide a review of the literature on the genetic basis of primary melanocytic tumors of the CNS.

Accuracy of Different Mini Nutritional Assessment Reduced Forms to Evaluate the Nutritional Status of Elderly Hospitalised Diabetic Patients

BACKGROUND

Disease-associated malnutrition (DAM) is a health problem involving all sanitary levels, especially hospitalised elderly patients. Different MNA (Mini Nutritional Assessment)-based forms have been validated in different settings, but it remains unclear if they are appropriate to evaluate the nutritional status of geriatric hospitalised patients with diabetes.

OBJECTIVE

The aim of this work was to analyse the accuracy of several MNA reduced forms to detect malnutrition in hospitalised elderly diabetic patients.

METHODS

A multicentre observational study was carried out in diabetic patients, who were over the age of 65, from 35 Spanish hospitals. Principal component analysis (PCA) selected the minimal components to elaborate the newly-proposed reduced new version of the MNA (r-MNA). Cohen's Kappa index (KI), with its 95% confidence interval (CI), was used to measure the agreement between the different reduced forms (r-MNA, MNA-SF-BMI, MNA-SF-CC, m-MNA) with the original MNA.

RESULTS

Five hundred and ninety-one elderly diabetic patients were included in the study. ROC analysis determined the following cut-off points for the newly proposed r MNA: 0-<10 "malnourished", 10-12 "at risk" and >12-15 "well-nourished". The upper cut-off point demonstrated a sensitivity of 87.7%, a specificity of 78.3% and an area under the curve of 0.93. The lower cut-off point showed a sensitivity of 95.9%, a specificity of 78.3% and an area under the curve of 0.95. The best agreement with the original MNA was observed for the MNA-SF-BMI (Κ index 80.7; 95% CI: 77.4-84) and the worst for the r-MNA (Κ index 72; 95% CI: 68.2-75.4).

CONCLUSIONS

This study found that MNA-SF-BMI is the most accurate screening tool for determining the nutritional status of hospitalised diabetic elderly patients. This is an easy-to-use, fast screening tool with a low risk of misclassification.

[Home parenteral nutrition in Spain 2011 and 2012; a report of the home and ambulatory artificial nutrition group NADYA]

OBJECTIVE

To report the data of the Home Parenteral Nutrition (HPN) registry of the NADYA-SENPE working group for the years 2011 and 2012.

METHODOLOGY

We compiled the data from the on-line registry introduced by reviewers of NADYA group responsible for monitoring of NPD introduced by since January 1, 2011 to december 31, 2012. Included fields were: age, sex, diagnosis and reason for HPN, access path, complications, beginning and end dates, complementary oral or enteral nutrition, activity level, autonomy degree, product and fungible material supply, withdrawal reason and intestinal transplant indication.

RESULTS

Year 2010: 184 patients from 29 hospitals , representing a rate of 3.98 patients/million inhabitants/ year 2011, with 186 episodes were recorded NPD . During 2012, 203 patients from 29 hospitals , representing a rate of 4.39 patients/million inhabitants/year 2012 , a total of 211 episodes were recorded NPD .

CONCLUSIONS

We observe an increase in registered patients with respect to previous years.Neoplasia remains as the main pathology since 2003. Although NADYA is consolidated registry and has been indispensable source of information relevant to the understanding of the progress of Home Artificial Nutrition in our country, there is ample room for improvement. Especially that refers to the registration of pediatric patients and the registration of complications.

[Translation and validation of the Spanish version of the EAT-10 (Eating Assessment Tool-10) for the screening of dysphagia]

RATIONALE

The Eating Assessment Tool-10 (EAT-10) is a self-administered, analogical, direct-scoring screening tool for dysphagia.

OBJECTIVE

To translate and adapt the EAT-10 into Spanish, and to evaluate its psychometric properties.

METHODS

After the translation and back-translation process of the EAT-10 ES, a prospective study was performed in adult patients with preserved cognitive and functional abilities. Patients in 3 clinical situations, diagnosed with dysphagia (DD), patients at risk of dysphagia (RD), and patients not at risk of dysphagia (SRD) were recruited from 3 settings: a hospital Nutritional Support Unit (USN), a nursing home (RG) and primary care centre (CAP). Patients completed the EAT-10 ES during a single visit. Both patients and researchers completed a specific questionnaire regarding EAT-10 ES' comprehension.

RESULTS

65 patients were included (age 75 ± 9.1 y), 52.3% women. Mean time of administration was 3.8 ± 1.7 minutes. 95.4% of patients considered that all tool items were comprehensible and 72.3% found it easy to assign scores. EAT-10 ES' internal consistency, Cronbach's Alpha coefficient was 0.87. A high correlation was observed between all tool items and global scores (p < 0.001). Mean score for patients in group DD was 15 ± 8.9 points, 6.7 ± 7.7 points in group RD, and 2 ± 3.1 points in group SRD. Male patients, previously diagnosed of dysphagia or patients from the NSU showed significantly higher scores on the EAT-10 ES (p < 0.001).

CONCLUSION

EAT-10 ES has proven to be reliable, valid and to have internal consistency. Is it an easy-to-understand tool that can be completed quickly, making it useful for the screening of dysphagia in routine clinical practice.

[The registry of home artificial nutrition and ambulatory of the Spanish Society of Parenteral and Enteral Nutrition; SWOT analysis]

OBJECTIVE

To evidence by means of a SWOT-R analysis performed by an expert consensus the most worrying characteristics of the register on Home-based and Outpatient Artificial Nutrition.

MATERIAL AND METHODS

SWOT-R analysis with expert consensus. We requested the participation of the active members of the NADYA group within the last 5 years with the premise of structuring the SWOT-R based on the characteristics of the NADYA registry from its beginning.

RESULTS

18 experts from hospitals all over Spain have participated. The internal analysis seems to be positive, presenting the registry as having important resources. The external analysis did not show a great number of threats, there are very potent factors, "the voluntariness" of the registry and the "dependence on external financing". The opportunities identified are important. The recommendations are aimed at stabilizing the system by decreasing the threats as one of the main focus of the strategies to develop as well as promoting the items identified as opportunities and strengths.

CONCLUSIONS

The analysis shows that the NADYA register shows a big potentiality for improvement. The proposed recommendations should be structured in order to stay on the track of development and quality improvement that has characterized the NADYA register from the beginning.

Prevalence of malnutrition and its etiological factors in hospitals

BACKGROUND

Malnutrition among inpatients is highly prevalent, and has a negative impact on their clinical outcome. The Working Group for the Study of Malnutrition in Hospitals in Catalonia was created to generate consensus guidelines for the prevention and/or treatment of malnutrition in hospitals in Catalonia, Spain.

AIMS

The objectives of the study were to determine the prevalence of malnutrition on admission to hospital in Catalonia and to assess relationships between malnutrition, social and demographic data, overall costs, and mortality.

METHODS

Prospective and multicenter study conducted with 796 patients from 11 hospitals representative of the hospitalized population in Catalonia. Nutritional status was evaluated using the Nutritional Risk Screening 2002 method.

RESULTS

Overall, 28.9% of the patients are malnourished or at nutritional risk. Elderly patients, non-manual workers, those admitted to hospital as emergencies and with higher co-morbidities had higher risk of malnutrition. The type of hospital (second level vs. tertiary or University referral) to which they were admitted was also a factor predisposing to malnutrition. Length of hospital stay was longer in malnourished patients (10.5 vs. 7.7 days, p < 0.0001). The need for a convalescent home on leaving hospital was higher as well as the risk of mortality (8.6% malnourished vs. 1.3% nonmalnourished, p < 0.0001).

CONCLUSIONS

The prevalence of malnutrition is high in patients on admission to hospital in our community, resulting in elevated overall costs and higher risk of mortality. Age, social class and characteristics of the Unit and the Hospital are the main factors involved in hospital malnutrition.

Multidisciplinary consensus on the approach to hospital malnutrition in Spain

RATIONALE

Disease-related malnutrition constitutes a highly prevalent healthcare problem with high costs associated. In Spain, the prevalence of malnutrition in hospitalized patients has been reported from 30% to 50%.

OBJECTIVES

Main purposes of this consensus document were to establish recommendations that facilitate decision-making and action to prevent and early-diagnose disease-related hospital malnutrition, on the management of nutritional support methods and actions to evaluate nutritional treatment compliance and efficacy.

METHODS

A systematic bibliographical search of authors was performed, complemented by updated bibliography by author references up to 2010. From this review, some recommendations were defined, modified and critically evaluated by the representatives of scientific societies in a consensus conference (Dec 2010) following a structured brainstorming technique: the Metaplan(®) technique. A double validation process was undertaken until final recommendations were obtained.

RESULTS

30 consensus recommendations for the prevention and management of hospital malnutrition are presented in this document. Recommendations cover all clinical care settings as well as prevention, screening, diagnosis, treatment and follow-up of disease-related malnutrition.

CONCLUSIONS

Nutritional screening is strongly recommended at all clinical settings when nutritional risk factors are identified or there is clinical suspicion of malnutrition. Nutritional assessment should be designed and performed according to centers' resources, but clearly identified protocols should be available.

[Meta-analysis on the role of lycopene in type 2 diabetes mellitus]

INTRODUCTION

lycopene is a carotene with a potent antioxidant effect found in tomato and its derivatives. Given that diabetic patients present an increased oxidative stress, lycopene could be beneficial. The aim of this scientific review has been to analyze the scientific evidence of the role of lycopene as an anti-oxidant agent in diabetes, its prevention and the metabolic control and development of complications.

MATERIALS AND METHODS

We carried out a systematic review and meta-analysis. A literature search was done in Medline and the Cochrane Library, using the MeSH terms "carotenoids" OR "lycopene" AND "type 2 diabetes mellitus". The search was manually completed from the references of the papers found. The quality of the studies was assessed by using the JADAD and STROBE scales. We included a total of 10 articles.

RESULTS

After adjusting for other risk factors, the OR for developing DM2 as similar among the different levels of lycopene intake. The plasma levels of lycopene increase in the intervention groups. Lycopene decreases the malonyldialdehyde and lipid peroxidation. The non-provitamin A/provitamin A carotenoids ratio is negatively associated with the risk for suffering from diabetic retinopathy.

CONCLUSION

Tomato or lycopene intake increases the plasma levels of this compound. However, there is no evidence for the association between lycopene intake and the risk for having diabetes. This compound and other tomato derivatives may have a beneficial effect on the oxidative stress in diabetic patients. The non-provitamin A/provitamin A carotenoids ratio is negatively associated with the risk for suffering from diabetic retinopathy, although there are no data available on the relationship between lycopene and other diabetic complications.
