Economic Analysis of a Ketoanalogue-Supplemented Very Low-Protein Diet in Patients With Chronic Kidney Disease in Taiwan and Thailand.

OBJECTIVE: A vegetarian very low-protein diet (VLPD) supplemented with ketoanalogues of essential amino acids Ketoanalogue-supplemented very low-protein diet (sVLPD) delays dialysis initiation in patients with chronic kidney disease (CKD). In this cost-effectiveness analysis, we compare an sVLPD with a conventional low-protein diet (LPD) in patients with CKD stage 4-5 using data from Taiwan and Thailand. DESIGN AND METHODS: A Markov model simulated health outcomes and care costs in patients receiving an sVLPD (0.3-0.4 g/kg-day, vegetarian diet) supplemented with ketoanalogues (1 tablet/5 kg-day) or an LPD (0.6 g/kg-day, mixed proteins). Health state transition probability and resource cost inputs were based on published literature and local sources, respectively. RESULTS: An sVLPD increased survival and quality-adjusted life years (QALYs) at a lower cost than an LPD. Total cost of care in Taiwan was 2,262,592.30 New Taiwan dollars (NTD) (68,059.35 EUR) with an LPD and 1,096,938.20 NTD (32,996.18 EUR) with an sVLPD (difference -1,165,654.10 NTD; -35,063.17 EUR). Total cost of care in Thailand was 500,731.09 Thai baht (THB) (14,584.12 EUR) with an LPD and 421,019.22 THB (12,262.46 EUR) with an sVLPD (difference -79,711.86 THB; -2,321.66 EUR). CONCLUSION: A ketoanalogue-supplemented vegetarian sVLPD increased QALYs and lowered lifetime care costs versus an LPD in patients with predialysis CKD in Taiwan and Thailand. These data, together with the new KDOQI Guidelines for nutrition in CKD, support dietary intervention using ketoanalogue-supplemented vegetarian sVLPDs to prevent CKD progression and postpone dialysis as a cost-effective approach, with beneficial effects for patients and health care providers.

A computational framework for modeling and studying pertussis epidemiology and vaccination.

BACKGROUND: Emerging and re-emerging infectious diseases such as Zika, SARS, ncovid19 and Pertussis, pose a compelling challenge for epidemiologists due to their significant impact on global public health. In this context, computational models and computer simulations are one of the available research tools that epidemiologists can exploit to better understand the spreading characteristics of these diseases and to decide on vaccination policies, human interaction controls, and other social measures to counter, mitigate or simply delay the spread of the infectious diseases. Nevertheless, the construction of mathematical models for these diseases and their solutions remain a challenging tasks due to the fact that little effort has been devoted to the definition of a general framework easily accessible even by researchers without advanced modelling and mathematical skills. RESULTS: In this paper we describe a new general modeling framework to study epidemiological systems, whose novelties and strengths are: (1) the use of a graphical formalism to simplify the model creation phase; (2) the implementation of an R package providing a friendly interface to access the analysis techniques implemented in the framework; (3) a high level of portability and reproducibility granted by the containerization of all analysis techniques implemented in the framework; (4) a well-defined schema and related infrastructure to allow users to easily integrate their own analysis workflow in the framework. Then, the effectiveness of this framework is showed through a case of study in which we investigate the pertussis epidemiology in Italy. CONCLUSIONS: We propose a new general modeling framework for the analysis of epidemiological systems, which exploits Petri Net graphical formalism, R environment, and Docker containerization to derive a tool easily accessible by any researcher even without advanced mathematical and computational skills. Moreover, the framework was implemented following the guidelines defined by Reproducible Bioinformatics Project so it guarantees reproducible analysis and makes simple the developed of new user-defined workflows.

Omega-3 fatty acid-containing parenteral nutrition in ICU patients: systematic review with meta-analysis and cost-effectiveness analysis.

BACKGROUND: Omega-3 (ω-3) fatty acid (FA)-containing parenteral nutrition (PN) is associated with significant improvements in patient outcomes compared with standard PN regimens without ω-3 FA lipid emulsions. Here, we evaluate the impact of ω-3 FA-containing PN versus standard PN on clinical outcomes and costs in adult intensive care unit (ICU) patients using a meta-analysis and subsequent cost-effectiveness analysis from the perspective of a hospital operating in five European countries (France, Germany, Italy, Spain, UK) and the US. METHODS: We present a pharmacoeconomic simulation based on a systematic literature review with meta-analysis. Clinical outcomes and costs comparing ω-3 FA-containing PN with standard PN were evaluated in adult ICU patients eligible to receive PN covering at least 70% of their total energy requirements and in the subgroup of critically ill ICU patients (mean ICU stay > 48 h). The meta-analysis with the co-primary outcomes of infection rate and mortality rate was based on randomized controlled trial data retrieved via a systematic literature review; resulting efficacy data were subsequently employed in country-specific cost-effectiveness analyses. RESULTS: In adult ICU patients, ω-3 FA-containing PN versus standard PN was associated with significant reductions in the relative risk (RR) of infection (RR 0.62; 95% CI 0.45, 0.86; p = 0.004), hospital length of stay (HLOS) (- 3.05 days; 95% CI - 5.03, - 1.07; p = 0.003) and ICU length of stay (LOS) (- 1.89 days; 95% CI - 3.33, - 0.45; p = 0.01). In critically ill ICU patients, ω-3 FA-containing PN was associated with similar reductions in infection rates (RR 0.65; 95% CI 0.46, 0.94; p = 0.02), HLOS (- 3.98 days; 95% CI - 6.90, - 1.06; p = 0.008) and ICU LOS (- 2.14 days; 95% CI - 3.89, - 0.40; p = 0.02). Overall hospital episode costs were reduced in all six countries using ω-3 FA-containing PN compared to standard PN, ranging from €-3156 ± 1404 in Spain to €-9586 ± 4157 in the US. CONCLUSION: These analyses demonstrate that ω-3 FA-containing PN is associated with statistically and clinically significant improvement in patient outcomes. Its use is also predicted to yield cost savings compared to standard PN, rendering ω-3 FA-containing PN an attractive cost-saving alternative across different health care systems.

Propofol vs. inhalational agents to maintain general anaesthesia in ambulatory and in-patient surgery: a systematic review and meta-analysis.

BACKGROUND: It is unclear if anaesthesia maintenance with propofol is advantageous or beneficial over inhalational agents. This study is intended to compare the effects of propofol vs. inhalational agents in maintaining general anaesthesia on patient-relevant outcomes and patient satisfaction. METHODS: Studies were identified by electronic database searches in PubMed™, EMBASE™ and the Cochrane™ library between 01/01/1985 and 01/08/2016. Randomized controlled trials (RCTs) of peer-reviewed journals were studied. Of 6688 studies identified, 229 RCTs were included with a total of 20,991 patients. Quality control, assessment of risk of bias, meta-bias, meta-regression and certainty in evidence were performed according to Cochrane. Common estimates were derived from fixed or random-effects models depending on the presence of heterogeneity. Post-operative nausea and vomiting (PONV) was the primary outcome. Post-operative pain, emergence agitation, time to recovery, hospital length of stay, post-anaesthetic shivering and haemodynamic instability were considered key secondary outcomes. RESULTS: The risk for PONV was lower with propofol than with inhalational agents (relative risk (RR) 0.61 [0.53, 0.69], p < 0.00001). Additionally, pain score after extubation and time in the post-operative anaesthesia care unit (PACU) were reduced with propofol (mean difference (MD) - 0.51 [- 0.81, - 0.20], p = 0.001; MD - 2.91 min [- 5.47, - 0.35], p = 0.03). In turn, time to respiratory recovery and tracheal extubation were longer with propofol than with inhalational agents (MD 0.82 min [0.20, 1.45], p = 0.01; MD 0.70 min [0.03, 1.38], p = 0.04, respectively). Notably, patient satisfaction, as reported by the number of satisfied patients and scores, was higher with propofol (RR 1.06 [1.01, 1.10], p = 0.02; MD 0.13 [0.00, 0.26], p = 0.05). Secondary analyses supported the primary results. CONCLUSIONS: Based on the present meta-analysis there are several advantages of anaesthesia maintenance with propofol over inhalational agents. While these benefits result in an increased patient satisfaction, the clinical and economic relevance of these findings still need to be addressed in adequately powered prospective clinical trials.

Mortality and morbidity after total intravenous anaesthesia versus inhalational anaesthesia: a systematic review and meta-analysis.

Background: General anaesthesia is provided to more than 300 million surgical patients worldwide, every year. It is administered either through total intravenous anaesthesia, using only intravenous agents, or through inhalational anaesthesia, using volatile anaesthetic agents. The debate on how this affects postoperative patient outcome is ongoing, despite an abundance of published trials. The relevance of this topic has grown by the increasing concern about the contribution of anaesthetic gases to the environmental impact of surgery. We aimed to summarise all available evidence on relevant patient outcomes with total intravenous anaesthesia versus inhalational anaesthesia. Methods: In this systematic review and meta-analysis, we searched PubMed/Medline, Embase and Cochrane Central Register of Controlled trials for works published from January 1, 1985 to August 1, 2023 for randomised controlled trials comparing total intravenous anaesthesia using propofol versus inhalational anaesthesia using the volatile anaesthetics sevoflurane, desflurane or isoflurane. Two reviewers independently screened titles, abstracts and full text articles, and assessed risk of bias using the Cochrane Collaboration tool. Outcomes were derived from a recent series of publications on consensus definitions for Standardised Endpoints for Perioperative trials (StEP). Primary outcomes covered mortality and organ-related morbidity. Secondary outcomes were related to anaesthetic and surgical morbidity. This study is registered with PROSPERO (CRD42023430492). Findings: We included 317 randomised controlled trials, comprising 51,107 patients. No difference between total intravenous and inhalational anaesthesia was seen in the primary outcomes of in-hospital mortality (RR 1.05, 95% CI 0.67-1.66, 27 trials, 3846 patients), 30-day mortality (RR 0.97, 95% CI 0.70-1.36, 23 trials, 9667 patients) and one-year mortality (RR 1.14, 95% CI 0.88-1.48, 13 trials, 9317 patients). Organ-related morbidity was similar between groups except for the subgroup of elderly patients, in which total intravenous anaesthesia was associated with a lower incidence of postoperative cognitive dysfunction (RR 0.62, 95% CI 0.40-0.97, 11 trials, 3834 patients) and a better score on postoperative cognitive dysfunction tests (standardised mean difference 1.68, 95% CI 0.47-2.88, 9 trials, 4917 patients). In the secondary outcomes, total intravenous anaesthesia resulted in a lower incidence of postoperative nausea and vomiting (RR 0.61, 95% CI 0.56-0.67, 145 trials, 23,172 patients), less emergence delirium (RR 0.40, 95% CI 0.29-0.56, 32 trials, 4203 patients) and a higher quality of recovery score (QoR-40 mean difference 6.45, 95% CI 3.64-9.25, 17 trials, 1835 patients). Interpretation: The results indicate that postoperative mortality and organ-related morbidity was similar for intravenous and inhalational anaesthesia. Total intravenous anaesthesia offered advantages in postoperative recovery. Funding: Dutch Society for Anaesthesiology (NVA).

CELESTIA: Cost-Effectiveness Analysis of Empagliflozin Versus Sitagliptin in Patients with Type 2 Diabetes in Greece.

Purpose: Globally, the prevalence of diabetes is on the rise, with the number of affected individuals predicted to cross 700 million by 2045. In Greece, in 2015, almost 700,000 people received prescribed medication for type 2 diabetes. The CELESTIA study aims to assess the cost-effectiveness of empagliflozin compared to branded sitagliptin in type 2 diabetes patients both with and without established cardiovascular disease in Greece from a third payer perspective. Methods: The IQVIA Core Diabetes Model was used and analyses were conducted from the Greek healthcare payer perspective. Patients received either empagliflozin or sitagliptin until HbA1c threshold of 8.5% (69 mmol/mol) was exceeded. Subsequently, patients were assumed to intensify to insulin therapy. Baseline cohort characteristics and treatment effects were derived from clinical trial data. Literature data were used for input (utilities, treatment costs and costs of diabetes-related complications costs). A lifetime time horizon (50 years) was applied, and costs and benefits were discounted at an annual rate of 3.5%. Results: Over a lifetime horizon, for empagliflozin, the estimated ICER was of €6,587 and €966 per quality-adjusted life years gained versus sitagliptin, in patients without established cardiovascular disease and in patients with established cardiovascular disease, respectively. Probabilistic sensitivity analysis confirmed the robustness of the analysis. Conclusion: The analysis demonstrated that for type 2 diabetes patients, empagliflozin is a cost-effective treatment option versus branded sitagliptin in Greece.

Economic Analysis of a Ketoanalogue-supplemented Very Low-protein Diet in Patients With Chronic Kidney Disease in Vietnam.

PURPOSE: The aim of this study was to estimate the cost-effectiveness of a very low-protein diet (VLPD) supplemented with ketoanalogues of essential amino acids compared with a conventional low-protein diet (LPD) in Vietnam. METHODS: The study was conducted from payer (base case), patient, and societal perspectives. A Markov model simulated costs and quality-adjusted life-years (QALYs) for patients with chronic kidney disease stage 4 or 5 (CKD4+) who were followed up during their lifetimes. Patients received a VLPD (0.3- to 0.4-g/kg/d diet) supplemented with ketoanalogues (5 kg/d [1 tablet]) versus LPD (0.6 g/kg/d, mixed proteins). In each model cycle, patient transitions among the health states-CKD4+ (nondialysis), dialysis, and death-were based on transition probabilities taken from the published literature. The time horizon covered the cohort's lifetime. Utilities and costs were estimated from literature review and projected for the lifespan considered in the model. Probabilistic and deterministic sensitivity analyses were performed. FINDINGS: The ketoanalogue-supplemented VLPD increased survival and QALYs compared with the LPD. From a payer's perspective, total cost of care in Vietnam was ₫216,854,268 (€8684/$9242) per patient with LPD versus ₫200,928,819 (€8046/$8563) per patient with a supplemented VLPD (sVLPD) (difference, -₫15,925,449 [-€638/-$679]). From a patient's perspective, total cost of care in Vietnam was ₫217,872,043 (€8724/$9285) per patient with LPD versus ₫116,015,672 (€4646/$4944) per patient with sVLPD (difference, -₫101,856,371 [-€4,079/ -$4341]). From a societal perspective, total cost of care in Vietnam was ₫434,726,312 (€17,408/-$18,527) per patient with LPD versus ₫316,944,491 (€12,692/ $13,508) per patient with sVLPD (difference, -₫117,781,820 [-€4716 €/$5020). IMPLICATIONS: Ketoanalogue-supplemented VLPD lowered costs compared with LPD in all 3 perspectives considered.

Cost-Impact Analysis of a Novel Diagnostic Test to Assess Community-Acquired Pneumonia Etiology in the Emergency Department Setting: A Multi-Country European Study.

BACKGROUND: We aimed to estimate the economic and clinical impacts of a novel diagnostic test called LIAISON® MeMed BV® (LMMBV), which can differentiate bacterial from viral infections, in patients with community-acquired pneumonia (CAP) in emergency departments. METHODS: A cost-impact simulation model was developed to investigate the financial consequences of the introduction of LMMBV into the standard of care (SOC) diagnostic process in Italy, Germany, and Spain. Clinical outcomes were expressed as antibiotic patients and days saved, reduced hospital admissions, and shortened hospital length of stay (LOS). Cost savings were evaluated from the perspectives of third-party payers and hospitals. A deterministic sensitivity analysis (DSA) was carried out. RESULTS: LMMBV was associated with a reduction in antibiotic prescriptions, treatment duration, and LOS. Furthermore, the adoption of LMMBV would allow savings per patient up to EUR 364 and EUR 328 for hospitals and EUR 91 and EUR 59 for payers in Italy and Germany, respectively. In Spain, average savings per patient could reach up to EUR 165 for both payers and hospitals. Savings were most sensitive to test accuracy, with DSA confirming the robustness of the results. CONCLUSIONS: Combining LMMBV with the current SOC diagnostic process is expected to provide clinical and economic benefits in Italy, Germany, and Spain.

Prevalence and economic cost of malnutrition in Italy: A systematic review and metanalysis from the Italian Society of Artificial Nutrition and Metabolism (SINPE).

OBJECTIVES: Disease-related malnutrition (DRM) is a major public health issue with dramatic consequences on outcomes. However, in Italy a comprehensive and updated overview on national prevalence, in both the adult and pediatric populations, and its burden on the health care environment, is missing. The aim of this systematic literature review and meta-analysis was to identify and summarize the available evidence regarding the prevalence of DRM in Italy from pediatric to adult and older ages, and to project its global costs on the health care system. METHODS: We performed a systematic literature search for articles on epidemiology of DRM in Italy published up to June 2021. Studies reporting data on the prevalence of DRM in community-dwelling individuals with chronic diseases, nursing home patients, and hospitalized patients (medical, surgery, and oncology patients), were selected for inclusion. Methodological quality of the studies was assessed by two independent reviewers using published criteria. An epidemiologic meta-analysis to obtain an aggregate estimate of prevalence of DRM was performed and a model for estimating the cost of illness, based on the application of epidemiologic results to official national hospitalization data, and attribution of relevant unit costs in the national context was constructed. RESULTS: Sixty-seven studies reporting on the prevalence of DRM in Italian populations were included in the final selection; meta-analytical pooling yields mean prevalence estimates of about 50% and 30% in adult and pediatric hospitalized populations, respectively, with even higher findings for residents of long-term care facilities. Modeled projections of DRM-attributable yearly economic effects on the Italian health care system exceed 10 billion € in base case analysis, with the most optimistic estimate still exceeding 2.5 billion €. CONCLUSION: Although comparable in magnitude to data from previous studies in analogous international settings, the diffusion and effects of DRM in the Italian setting is impressive. Increased awareness of these data and proactive fostering of clinical nutrition services are warranted, as prompt identification and treatment of malnutrition have been shown to effectively improve clinical and economic results.

State-of-the-art review on AL amyloidosis in Western Countries: Epidemiology, health economics, risk assessment and therapeutic management of a rare disease.

Amyloidosis is the term to define a broad array of rare protein misfolding syndromes. Among them, light chain (AL) amyloidosis is the most common, affecting roughly 10 people per million/year. The core purpose of the present literature review is to shed light on the academic and clinical knowledge on the condition, encompassing its i) epidemiology, ii) economic burden, and iii) quality of life consequences. The areas of interest are Europe and North America. Literature search was primarily performed on Embase® and finally integrated with additional, deemed eligible, sources. Pre-defined PICOS criteria were employed for the inclusion and exclusion processes. A total of 64 studies were comprehensively included in the current literature review as compliant with the inclusion criteria. The results were presented according to the outcomes of interest and eventually triangulated and compared to available literature studies. A broad picture on the main aspects of AL amyloidosis is delivered.

Cost-utility analysis of real-time artificial intelligence-assisted colonoscopy in Italy.

Background and study aims Artificial intelligence (AI)-assisted colonoscopy has proven to be effective compared with colonoscopy alone in an average-risk population. We aimed to evaluate the cost-utility of GI GENIUS, the first marketed real-time AI system in an Italian high-risk population. Methods A 1-year cycle cohort Markov model was developed to simulate the disease evolution of a cohort of Italian individuals positive on fecal immunochemical test (FIT), aged 50 years, undergoing colonoscopy with or without the AI system. Adenoma or colorectal cancer (CRC) were identified according to detection rates specific for each technique. Costs were estimated from the Italian National Health Service perspective. Results Colonoscopy+AI system was dominant with respect to standard colonoscopy. The GI GENIUS system prevented 155 CRC cases (-2.7%), 77 CRC-related deaths (-2.8%), and improved quality of life (+0.027 QALY) with respect to colonoscopy alone. The increase in screening cost (+€10.50) and care for adenoma (+€3.53) was offset by the savings in cost of care for CRC (-€28.37), leading to a total savings of €14.34 per patient. Probabilistic sensitivity analysis confirmed the cost-efficacy of the AI system (almost 80% probability). Conclusions The implementation of AI detection tools in colonoscopy after patients test FIT-positive seems to be a cost-saving strategy for preventing CRC incidence and mortality.

Omega-3 fatty acids in parenteral nutrition - A systematic review with network meta-analysis on clinical outcomes.

BACKGROUND & AIMS: Accumulating scientific evidence supports the benefits of parenteral nutrition (PN) with fish oil (FO) containing intravenous lipid emulsions (ILEs) on clinical outcomes. Yet, the question of the most effective ILE remains controversial. We conducted a network meta-analysis (NMA) to compare and rank different types of ILEs in terms of their effects on infections, sepsis, ICU and hospital length of stay, and in-hospital mortality in adult patients. METHODS: MEDLINE, EMBASE, and Web of Science databases were searched for randomized controlled trials (RCTs) published up to May 2022, investigating ILEs as a part of part of PN covering at least 70% of total energy provision. Lipid emulsions were classified in four categories: FO-ILEs, olive oil (OO)-ILEs, medium-chain triglyceride (MCT)/soybean oil (SO)-ILEs, and pure SO-ILEs. Data were statistically combined through Bayesian NMA and the Surface Under the Cumulative RAnking (SUCRA) was calculated for all outcomes. RESULTS: 1651 publications were retrieved in the original search, 47 RCTs were included in the NMA. For FO-ILEs, very highly credible reductions in infection risk versus SO-ILEs [odds ratio (OR) = 0.43 90% credibility interval (CrI) (0.29-0.63)], MCT/soybean oil-ILEs [0.59 (0.43-0.82)], and OO-ILEs [0.56 (0.33-0.91)], and in sepsis risk versus SO-ILEs [0.22 (0.08-0.59)], as well as substantial reductions in hospital length of stay versus SO-ILEs [mean difference (MD) = -2.31 (-3.14 to -1.59) days] and MCT/SO-ILEs (-2.01 (-2.82 to -1.22 days) were shown. According to SUCRA score, FO-ILEs were ranked first for all five outcomes. CONCLUSIONS: In hospitalized patients, FO-ILEs provide significant clinical benefits over all other types of ILEs, ranking first for all outcomes investigated.

Benefits of MR-proADM-guided decision-making in the emergency department: clinical and economic evaluation in Italy, Germany, Spain, and the UK.

AIM: In a randomized control trial mid-regional proadrenomedullin (MR-proADM)-guided decision-making has been proven to safely reduce hospital admissions based on an accurate assessment of disease severity in the Emergency Department (ED). This study aimed to assess the impact of a MR-proADM-Guided Triage (MR-GT) versus standard Hospital Triage (HT) on clinical and economic outcomes in ED patients with suspected infection in Spain, Italy, Germany, and the UK, using Patient-Level Data (PLD) from two observational studies. METHODS: PLD was collected from patients enrolled at a Spanish hospital during two observational studies. Logistic regression was used to identify predictors of hospitalization. A patient-level simulation model was subsequently developed to evaluate the clinical and economic impact of MR-GT versus HT using results from the statistical analysis and country-specific cost data from the published literature. Probabilistic and deterministic sensitivity analyses were carried out. RESULTS: Four hundred seventy-three patients were enrolled in this study. MR-proADM had the strongest association with hospital admission, followed by age and National Early Warning Score (NEWS). In the simulation model, MR-GT was associated with an overall reduction in hospitalization relative to HT, equal to 22.6 percentage points (40.9 vs. 63.5%). In addition, the use of MR-GT would reduce the total hospital cost per patient presenting to the ED with suspected infection by roughly 30%, with a mean cost saving per patient of €626, €1,484, €1,154, and £1,113 in Spain, Italy, Germany, and the UK, respectively. The robustness of these findings was confirmed by sensitivity analyses. LIMITATIONS: The statistical analyses were not performed on the same population simulated in the model. Clinical input parameters were assumed to be the same for all countries. CONCLUSIONS: MR-proADM showed to be the main predictor of hospitalization. An MR-proADM decision algorithm provides cost savings in Spain, Italy, Germany, and the UK.

Liquid biopsy comprehensive genomic profiling of lung cancer in the Italian population: A real-world experience.

OBJECTIVES: Liquid biopsy with next-generation sequencing (NGS) has emerged as a promising tool for tumor mutation profiling. In this study, we describe the genomic profile of Italian lung cancer patients tested with blood-based comprehensive genomic profiling (CGP) to assess the genomic landscape complexity and its impact on enhancing treatment options for patients. MATERIALS AND METHODS: Between January 2021 and December 2021, a total of 229 lung cancer patients were profiled by FoundationOne®Liquid CDx (F1LCDx®) assay on circulating tumor DNA (ctDNA). F1LCDx® reports alterations across 324 cancer-related genes and genomic signatures, including tumor fraction (TF) and blood-based tumor mutational burden (bTMB). Detected variants were classified according to the ESMO Scale of Clinical Actionability for molecular Targets (ESCAT). RESULTS: 90.4% of patients had at least one detectable alteration in plasma. The most frequently mutated genes were TP53 (47.6%), DNMT3A (33.2%), EGFR (20.1%), and KRAS (15.7%). Elevated TF was detected in 18.3% of patients, suggesting high reliability of test results. According to the ESCAT classification, potentially actionable alterations (Tier I-II) were identified in 27.1% of samples. An additional 5.2% harbored an alteration for which an approved drug is available in other cancer types (Tier III). Furthermore, 13.1% of tumors exhibited high bTMB, which may predict response to immunotherapy. Overall, 156 (68.1%) patients were eligible for enrolment in clinical trials. CONCLUSION: Liquid biopsy NGS is a viable and valuable approach to guide personalized therapy. The use of blood-based CGP may help identify a larger number of actionable mutations and increase chances of enrolment in clinical trials.

Improved efficiency of daratumumab treatment of multiple myeloma adopting the subcutaneous route: A micro-costing analysis in three Italian hematology centers.

BACKGROUND: Daratumumab is a humanized monoclonal antibody approved for the treatment of adult patients with newly diagnosed or relapsed/refractory multiple myeloma (RRMM). Subcutaneous (SC) formulation proved to be non-inferior in comparison with intravenous (IV) administration route. This study aimed at assessing the economic and time impact associated with the use of SC versus IV daratumumab in patients with RRMM from the perspective of the hematology center. METHODS: This was a 5-month multicenter time-and-motion cross-sectional micro-costing study conducted in three Italian hematology centers among adult patients diagnosed with RRMM with ongoing treatment with IV or SC daratumumab. Measurements were performed by an ad hoc App. RESULTS: Nineteen (20%) IV and 76 (80%) SC administration procedures were measured. Patients spent a mean of 4.85 ± 0.91 or 1.08 ± 0.56 h in the hematology center to receive IV or SC daratumumab, respectively. Healthcare professionals (HCPs) spent a mean of 49.38 ± 16.13 and 20.37 ± 7.88 min of active working time to manage IV and SC administrations, respectively. The infusion chair was occupied for a mean of 4.85 ± 0.91 and 0.99 ± 0.55 h during IV or SC administration, respectively. On average, considering the costs due to HCP and chair time, materials, and overhead costs, every IV and SC administration costed €80.33 and 34.90, respectively. CONCLUSIONS: In conclusion, as compared with IV administration, SC daratumumab was associated with 78%, 59%, 80% savings in terms of patient time, HCP active working time, and infusion chair, respectively, and 56.6% budget savings.

n-3 fatty acid-enriched parenteral nutrition regimens in elective surgical and ICU patients: a meta-analysis.

INTRODUCTION: Previous studies and a meta-analysis in surgical patients indicate that supplementing parenteral nutrition regimens with n-3 polyunsaturated fatty acids (PUFAs), in particular eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), is associated with improved laboratory and clinical outcomes in the setting of hyper-inflammatory conditions. Refined or synthetic fish oils are commonly used as a source of EPA and DHA. The objective of the present meta-analysis was to evaluate n-3 PUFA-enriched parenteral nutrition regimens in elective surgical and intensive care unit (ICU) patients. METHODS: Medline was searched for randomized controlled trials comparing n-3 PUFA-enriched lipid emulsions with standard non-enriched lipid emulsions (i.e. soybean oil, MCT/LCT or olive/soybean oil emulsions) in surgical and ICU patients receiving parenteral nutrition. Extracted data were pooled by means of both random and fixed effects models, and subgroup analyses were carried forward to compare findings in ICU versus non-ICU patients. RESULTS: A total of 23 studies (n = 1502 patients: n = 762 admitted to the ICU) were included. No statistically significant difference in mortality rate was found between patients receiving n-3 PUFA-enriched lipid emulsions and those receiving standard lipid emulsions (RR = 0.89; 0.59, 1.33), possibly reflecting a relatively low underlying mortality risk. However, n-3 PUFA-enriched emulsions are associated with a statistically and clinically significant reduction in the infection rate (RR = 0.61; 0.45, 0.84) and the lengths of stay, both in the ICU (-1.92; -3.27, -0.58) and in hospital overall (-3.29; -5.13, -1.45). Other beneficial effects included reduced markers of inflammation, improved lung gas exchange, liver function, antioxidant status and fatty acid composition of plasma phospholipids, and a trend towards less impairment of kidney function. CONCLUSIONS: These results confirm and extend previous findings, indicating that n-3 PUFAs-enriched parenteral nutrition regimens are safe and effective in reducing the infection rate and hospital/ICU stay in surgical and ICU patients.

A 36-month study on the cost/utility of add-on omalizumab in persistent difficult-to-treat atopic asthma in Italy.

OBJECTIVE: Omalizumab is a biological treatment for difficult-to-treat allergic asthma. Its mechanism of action relies on impeding the binding of immunoglobulin E (IgE) to specific cellular receptors, thus blocking the inflammatory cascade. At present, no long-term data are available on its cost/effectiveness. The aim of this study is to assess long-term clinical outcomes and to measure the cost/utility of long-term omalizumab use in difficult-to-treat allergic asthmatics. METHODS: The clinical, economic, and quality-of-life (QoL) outcomes of 36-month add-on omalizumab therapy were compared to equivalent outcomes for the year before the therapy's introduction in a cohort (n = 16) of adults with severe uncontrolled atopic asthma on chronic high-dose antiasthma treatments. The variables considered were lung function, IgE levels, health status, Asthma Control Test (ACT) score, QoL (St. George Questionnaire), general practitioner (GP) and specialist visits, number and duration of hospitalizations, emergency room admission, and pharmacological treatment (both dose and duration). Derived calculated indicators were changes in health-related QoL, total healthcare costs, and incremental cost/utility. Data from the two periods were tested for statistically significant differences according to Student's t test and p < .05 was accepted. RESULTS: Add-on omalizumab significantly and progressively improved asthma control and patient health-related QoL. Symptomatic drug and hospital care costs for these patients dropped significantly. A €450 increase in overall monthly costs was observed; however, when health benefits were considered, this cost increase translated into an incremental cost/utility ratio of €23,880 per quality-adjusted life year gained, which is quite a favorable and convenient figure in terms of the willingness to pay for health benefits in industrialized countries. CONCLUSIONS: The 36-month add-on omalizumab therapy persistently improved all clinical outcomes in difficult-to-treat asthmatic patients. Costs were also optimized and related to the extent of long-term health benefits achieved.

Effectiveness and cost-effectiveness of supplemental glutamine dipeptide in total parenteral nutrition therapy for critically ill patients: a discrete event simulation model based on Italian data.

INTRODUCTION: The supplementation of alanyl-glutamine dipeptide in critically ill patients necessitating total parenteral nutrition (TPN) improves clinical outcomes, reducing mortality, infection rate, and shortening intensive care unit (ICU) hospital lengths of stay (LOSs), as compared to standard TPN regimens. METHODS: A Discrete Event Simulation model that incorporates outcomes rates from 200 Italian ICUs for over 60,000 patients, alanyl-glutamine dipeptide efficacy data synthesized by means of a Bayesian random effects meta-analysis, and national cost data has been developed to evaluate the alternatives from the cost perspective of the hospital. Simulated clinical outcomes are death and infection rates in ICU, death rate in general ward, and hospital LOSs. Sensitivity analyses are performed by varying all uncertain parameter values in a plausible range. RESULTS: The internal validation process confirmed the accuracy of the model in replicating observed clinical data. Alanyl-glutamine dipeptide on average results more effective and less costly than standard TPN: reduced mortality rate (24.6% ± 1.6% vs. 34.5% ± 2.1%), infection rate (13.8% ± 2.9% vs. 18.8% ± 3.9%), and hospital LOS (24.9 ± 0.3 vs. 26.0 ± 0.3 days) come at a lower total cost per patient (23,409 ± 3,345 vs. 24,161 ± 3,523 Euro).Treatment cost is completely offset by savings on ICU and antibiotic costs. Sensitivity analyses confirmed the robustness of these results. CONCLUSIONS: Alanyl-glutamine dipeptide is expected to improve clinical outcomes and to do so with a concurrent saving for the Italian hospital.

Economic burden of hospital malnutrition: A cost-of-illness model.

BACKGROUND & AIMS: Hospital malnutrition is a highly prevalent condition that leads to an increased risk of clinical complications and a corresponding increase in healthcare resource utilisation. Despite the high prevalence and adverse clinical consequences, limited data are available on the magnitude of the economic burden associated with hospital malnutrition in Asian countries. The aim of the present analysis was to calculate country-specific estimates of the economic burden of hospital malnutrition in Asia. METHODS: Country-specific cost and prevalence data were used to calculate the incremental healthcare costs attributable to hospital malnutrition in 11 countries in Asia. The cost-of-illness was evaluated from the public perspective. Sources of increased cost included increased length of stay (LOS) and increased antibiotic use in malnourished patients who develop a healthcare-associated infection. Costs were calculated separately for the ward and intensive care unit (ICU) and currencies were converted to US$ to facilitate comparison. RESULTS: The estimated annual economic burden attributable to hospital malnutrition in Asia is $30.1 billion. Increased LOS accounts for the largest portion of the incremental cost, totalling $23.2 billion (77.2%) in the ward and $3.5 billion (11.5%) in the ICU. Medication costs related to the treatment of infectious complications account for an additional $3.4 billion (11.3%). Countries with the highest incremental costs include Japan ($19 billion), South Korea ($2.5 billion), and Taiwan ($2.2 billion). CONCLUSIONS: Hospital malnutrition imposes a substantial economic burden on Asian countries, resulting in an estimated $30 billion per year in additional healthcare costs. This finding underscores the need for rigorous screening and assessment as well as continuous monitoring of nutrition status in hospitalised patients to facilitate early identification and proactive management of hospital malnutrition.

Medium-Chain Triglyceride (MCT) Content of Adult Enteral Tube Feeding Formulas and Clinical Outcomes. A Systematic Review.

Available data on the effect of lipid composition of enteral formulas on clinical outcomes are controversial. The present systematic review was performed in order to verify whether the presence of specific lipidic substrates, namely medium-chain triglycerides (MCT), in enteral tube feeding formulas is associated to measurable clinical benefits in patients receiving enteral nutrition in different clinical settings, including home enteral nutrition (HEN). The results of this systematic review highlight a lack of robust evidence supporting the use of specific types of lipids in standard or disease-specific formulas. Evidence exists, however, that MCT-containing formulas are safe and well-tolerated. Further, well-designed, adequately powered, randomized controlled trials would be needed in order to assess the superiority of MCT- containing enteral formulas over other standard or disease-specific commercially available enteral products.
