RESUMO

BACKGROUND: Valsartan is commonly used for cardiac conditions. In 2018, the Food and Drug Administration recalled generic valsartan due to the detection of impurities. Our objective was to determine if heart failure patients receiving valsartan at the recall date had a greater likelihood of unfavorable outcomes than patients using comparable antihypertensives. METHODS: We conducted a cohort study of Optum's de-identified Clinformatics® Datamart (July 2017-January 2019). Heart failure patients with commercial or Medicare Advantage insurance who received valsartan were compared to persons who received non-recalled angiotensin receptor blockers (ARBs) and angiotensin converting enzyme-inhibitors (ACE-Is) for 1 year prior and including the recall date. Outcomes included a composite for all-cause hospitalization, emergency department (ED), and urgent care (UC) use and a measure of cardiac events which included hospitalizations for acute myocardial infarction and hospitalizations/ED/UC visits for stroke/transient ischemic attack, heart failure or hypertension at 6-months post-recall. Cox proportional hazard models with propensity score weighting compared the risk of outcomes between groups. RESULTS: Of the 87 130 adherent patients, 15% were valsartan users and 85% were users of non-recalled ARBs/ACE-Is. Valsartan use was not associated with an increased risk of all-cause hospitalization/ED/UC use six-months post-recall (HR 1.00; 95% CI 0.96-1.03), compared with individuals taking non-recalled ARBs/ACE-Is. Similarly, cardiac events 6-months post-recall did not differ between individuals on valsartan and non-recalled ARBs/ACE-Is (HR 1.04; 95% CI 0.97-1.12). CONCLUSIONS: The valsartan recall did not affect short-term outcomes of heart failure patients. However, the recall potentially disrupted the medication regimens of patients, possibly straining the healthcare system.

RESUMO

AIMS: Angiotensin receptor neprilysin inhibitor (ARNI) therapy is a cornerstone in the treatment of heart failure with reduced ejection fraction (HFrEF), with significant improvement in mortality as well as morbidity and quality of life. However, maximal ARNI doses often result in hypotension. Recent studies with 'real world' experience suggest that lower doses of ARNI are as effective as higher doses.In order to evaluate the symptomatic effect of low-dose ARNI in HFrEF patients, we analyzed physical activity data obtained via home monitoring of patients with cardiac implantable electronic devices (CIEDs). METHODS: We retrospectively analyzed physical activity data obtained from HFrEF patients with CIED-active home monitoring during the years 2021-2022. Patients with ARNI therapy were further divided into subgroups according to the administered dose. Low-dose ARNI included doses of up to 24/26 mg sacubitril/valsartan daily. Intermediate dose and high dose included doses of 72/78-120/130 mg/day, and 144/156-194/206 mg/day, respectively. RESULTS: A total of 122 patients had home monitoring-compatible CIEDs and HFrEF during the study period. Sixty-four of these patients were treated with ARNI. Administration of low-dose ARNI resulted in a 20% increase in daily activity when compared with patients without ARNI treatment ( P  = 0.038). Change in physical activity of patients in the intermediate-dose and high-dose groups was not significant. Younger patients, patients with cardiac resynchronization therapy, and patients without diabetes mellitus were more physically active. CONCLUSION: Low-dose ARNI had a beneficial effect on physical activity in HFrEF patients. MH via CIED provided real-life objective data for patients' follow-up.

RESUMO

This critical review of Kaddoura et al.'s article on sacubitril/valsartan in heart failure patients underscores the importance of considering potential adverse effects, including renal failure, hyperkalemia, angioedema, and increased reports of sudden cardiac death. It highlights the need for rigorous monitoring and precise treatment regimens, especially in diabetic heart failure patients. Additionally, the review questions the generalizability of the study's results to diverse healthcare settings and emphasizes the importance of grounded patient follow-up data for accurate long-term assessment. These considerations are vital for informed decision-making regarding sacubitril/valsartan use in heart failure management.

RESUMO

OBJECTIVE: To describe healthcare resource utilization (HCRU) and costs, in patients with newly diagnosed heart failure (HF) according to ejection fraction (EF) in Spain. METHODS: Retrospective cohort study that analyzed anonymized, integrated and computerised medical records in Spain. Patients with ≥ 1 new HF diagnosis between January 2013 and September 2019 were included and followed-up during a 4-year period. Rates per 100 person-years of HCRU and costs were estimated. RESULTS: Nineteen thousand nine hundred sixty-one patients were included, of whom 43.5%, 26.3%, 5.1% and 25.1% had HF with reduced, preserved, mildly reduced and unknown EF, respectively. From year 1 to 4, HF rates of outpatient visits decreased from 1149.5 (95% CI 1140.8-1159.3) to 765.5 (95% CI 745.9-784.5) and hospitalizations from 61.7 (95% CI 60.9-62.7) to 15.7(14.7-16.7) per 100 person-years. The majority of HF-related healthcare resource costs per patient were due to hospitalizations (year 1-4: 63.3-38.2%), followed by indirect costs (year 1-4: 12.2-29.0%), pharmacy (year 1-4: 11.9-19.9%), and outpatient care (year 1-4: 12.6-12.9%). Mean (SD) per patient HF-related costs decreased from 2509.6 (3518.5) to 1234.6 (1534.1) Euros (50% cost reduction). At baseline, 70.1% were taking beta-blockers, 56.3% renin-angiotensin system inhibitors, 11.8% mineralocorticoid receptor antagonists and 8.9% SGLT2 inhibitors. At 12 months, these numbers were 72.3%, 65.4%, 18.9% and 9.8%, respectively. CONCLUSIONS: Although the economic burden of HF decreased over time since diagnosis, it is still substantial. This reduction could be partially related to a survival bias (sick patients died early), but also to a better HF management. Despite that, there is still much room for improvement.

RESUMO

The study aimed to analyse the adverse drug reactions report form data received by the State Expert Center of the Ministry of Health of Ukraine from healthcare professionals in the Lviv region in 2022. Regarding specific types of medicines, the ones with proven cause-and-effect relationships that caused the highest frequency of adverse drug reactions incidents were chemotherapeutic agents (35.5%), medicines affecting the cardiovascular system (20.3%), and non-steroidal anti-inflammatory drugs (8%). Within the penicillin class, amoxicillin potentiated by clavulanate (67%) and amoxicillin (29%) were the dominant drugs showing the highest incidence rate of adverse reactions. Among cephalosporins, ceftriaxone (46%) and cefixime (15%) were found to take the lead in terms of adverse reaction frequency. The highest proportion among all adverse drug reactions caused by penicillins and cephalosporins was attributed to allergic reactions. To confirm or rule out immediate or delayed type allergies in patients, as well as in patients with a history of immediate-type allergic reactions to ß-lactams and planned administration of another ß-lactam, it is necessary to conduct skin testing (skin prick test, or, in the case of parenteral administration, intradermal test) with the planned ß-lactam antibiotic. The second highest proportion of induced adverse drug reactions was attributed to drugs affecting the cardiovascular system (20.3%). The leading medications in the angiotensin-converting enzyme inhibitors category were enalapril (47%) and the combination of lisinopril with hydrochlorothiazide (24%). In the angiotensin II receptor blockers category of medications, valsartan (30%) and telmisartan-hydrochlorothiazide combination (20%) ranked highest. In the category of CCB drugs, amlodipine (66%) and nifedipine (20%) held the leading positions. among angiotensin-converting enzyme inhibitors, enalapril caused the most prevalent and predicted adverse reaction, that of cough, affecting 10.5% of patients, whereas, with the combination therapy of lisinopril and hydrochlorothiazide, the cough was observed in only 5.2% of patients. Angiotensin II receptor blockers have a better safety profile, particularly concerning cough. Analysis of adverse drug reactions reports for angiotensin II receptor blockers showed no cases of cough with valsartan and telmisartan-hydrochlorothiazide combination. Among calcium channel blocker medications, amlodipine emerged to rank highest, causing one of the predicted adverse drug reactions, that of lower extremity oedema in 64% of patients. The second position was taken by the combination of amlodipine with valsartan, which showed a statistically significant reduction of 14.3% (p≤0.05) in the incidence of oedema. Using amlodipine at a dose of 5 mg in combination with sartan medicines as angiotensin receptor blockers is an effective therapeutic alternative not only for enhancing blood pressure control in hypertensive patients but also for improving the safety profile of amlodipine. Among all the non-steroidal anti-inflammatory drugs prescribed to patients in the Lviv region in 2022, the highest number of adverse reactions was associated with the administration of diclofenac, ibuprofen, paracetamol, and nimesulide, causing adverse drug reactions in 22%, 19%, 17%, and 10% of cases, respectively. The most common systemic manifestations of adverse reactions with these non-steroidal anti-inflammatory drugs were allergic reactions (63.4%) and gastrointestinal disorders (26.8%). From an evidence-based medicine perspective, the most justified approach for primary and secondary prevention of gastrointestinal complications is the use of proton pump inhibitors.

RESUMO

In this study, the presence of 23 pharmaceutically active compounds (PhACs) including antibiotics, analgesics, anti-inflammatories, psychiatric and cardiovascular drugs, antifungals and metabolites was investigated in surface waters. A total of 89 samples were collected during 3 years (2020, 2021 and 2022) from a European representative river basin (Tagus, Spain). To elucidate PhAC potential sources, sampling points located in areas with low, median and high anthropogenic influence were selected. The analytical method based on solid phase extraction (SPE) followed by UHPLC-MS/MS analysis was validated meeting SANTE/2020/12830 and SANTE/12682/2019 performance criteria. PhACs were quantified above limits of quantification (LOQs) in 96 % of water samples, being the antihypertensives valsartan (648 ng/L, 87 % quantification frequency) and irbesartan (390 ng/L, 75 %) and the antidepressant o-desmethylvenlafaxine (495 ng/L, 76 %) the predominant pollutants. The rest of the target PhACs showed median concentrations between 4 and 172 ng/L with quantification frequencies ranging from 35 to 75 %. ∑PhAC concentrations did not show temporal or seasonal trends. However, valsartan and naproxen presented lower levels in drier (spring and summer) compared to the wetter. Source identification revealed a clear anthropogenic origin since concentrations obtained in highly populated areas were statistically higher (p < 0.01) than those quantified in sparsely populated ones. This finding was also confirmed by calculating PhACs mass flow rates, which ranged between 1.4 and 235 kg/y. Finally, data generated were used to estimate the potential risk to the aquatic ecosystem for three trophic levels (phototrophic, invertebrate and vertebrate organisms). Risk quotient ratios (RQs) were calculated for all PhACs at the median (P50) and worst-case (max) scenarios. Up to 7 PhACs (acetaminophen, carbamazepine, gemfibrozil, ibuprofen, irbesartan, ketoprofen and venlafaxine) showed high risk for the highest trophic level (fish) in >45 % of investigated locations.

RESUMO

BACKGROUND: The 2022 clinical guidelines for management of heart failure with reduced ejection fraction call for quadruple therapy. Quadruple therapy consists of an angiotensin receptor-neprilysin inhibitor (ARNi), sodium-glucose cotransporter-2 inhibitor (SGLT2i), mineralocorticoid receptor antagonist, and beta blocker. The ARNi and sodium-glucose cotransporter-2 inhibitor are newer additions to standard of care with the ARNi replacing ACE (angiotensin-converting enzyme) inhibitors and angiotensin II receptor blockers. METHODS: We investigate the cost-effectiveness of sequentially adding the SGLT2i and ARNi to form quadruple therapy as compared with the previous standard of care with ACE inhibitor/mineralocorticoid receptor antagonist/beta blocker. Using a 2-stage Markov model, we projected the expected lifetime discounted costs and quality-adjusted life years (QALYs) of a simulated cohort of US patients who underwent each treatment option and calculated incremental cost-effectiveness ratios. We assessed incremental cost-effectiveness ratios using criteria for health care value (<$50 000/quality-adjusted life year [QALY] indicating high-value, $50 000-150 000/QALY indicating intermediate value, and >$150 000/QALY indicating low-value) and a standard $100 000/QALY cost-effectiveness threshold. RESULTS: Compared with the previous standard of care, the SGLT2i addition had an incremental cost-effectiveness ratio of $73 000/QALY and weakly dominated the ARNi addition. The addition of both the ARNi and SGLT2i for quadruple therapy offered 0.68 additional discounted QALYs over the SGLT2i addition alone at a lifetime discounted cost of $66 700, resulting in an incremental cost-effectiveness ratio of $98 500/QALY. In sensitivity analysis varying drug prices, the incremental cost-effectiveness ratio for quadruple therapy ranged from $73 500/QALY using prices available to the US Department of Veterans Affairs to $110 000/QALY using drug list prices. CONCLUSIONS: While quadruple therapy offers intermediate value, it is borderline cost effective compared with adding the SGLT2i alone to previous standard of care. Thus, its cost-effectiveness is sensitive to a payer's ability to negotiate discounts off the increasing list prices for ARNI and SGLT2is. The demonstrated benefits of ARNi and SGLT2is should be weighed against their high prices in payer and policy considerations.

RESUMO

Value-based care is the foundation of population health. The Health care Economic Efficiency Ratio (HEERO) scoring system is a promising new tool to measure the cost benefits of care in our Accountable Care Organization. HEERO score compares actual costs spent (utilizing insurance claims) and expected costs spent (estimated using the Centers for Medicare/Medicaid Services Risk score). Scores <1 suggest economic benefit. Sacubitril/valsartan has been shown to decrease readmissions for patients with heart failure (HF) and decrease health care costs. We explored the utility of sacubitril/valsartan in reducing HEERO scores and decreasing overall health care expenditure in patients with HF. Patients with HF in the population health cohort were enrolled. HEERO score was calculated for patients taking sacubitril/valsartan and other HF medications at 3-month intervals up to a year. We compared the average and total health care expenditure and inpatient days for patients on sacubitril/valsartan, spironolactone, ß blocker (BB) along with spironolactone, BB and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker. For patients on sacubitril/valsartan, HEERO scores and inpatient days decreased (decreased health care expenditure) as the number of days of utilization increased (p <0.0001). In total, 270+ days of sacubitril/valsartan decreased health care costs by 22%. This cost reduction was mainly attributed to decreased inpatient days. Additionally, the combination of sacubitril/valsartan, spironolactone, and BB showed decreased HEERO score and inpatient days compared with spironolactone, BB and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker in male patients. Sacubitril/valsartan use beyond 270 days resulted in decreased health care expenditure in a population health cohort compared with other HF medications. This economic benefit is achieved through the reduction in hospitalizations. Sacubitril/valsartan is an integral part of value-based care providing high-value, cost-effective care, and bolstering the economic wellbeing of patient care. Payor sources should consider this in subsidizing the cost of the medicine.

RESUMO

BACKGROUND: There are few contemporary data on outcomes, costs, and treatment following a hospitalization for heart failure (hHF) in epidemiologically representative cohorts. OBJECTIVES: This study sought to describe rehospitalizations, hospitalization costs, use of guideline-directed medical therapy (GDMT) (renin-angiotensin system inhibitors, sacubitril/valsartan, beta-blockers, mineralocorticoid receptor antagonists, and sodium-glucose cotransporter-2 inhibitors), and mortality after hHF. METHODS: EVOLUTION HF (Utilization of Dapagliflozin and Other Guideline Directed Medical Therapies in Heart Failure Patients: A Multinational Observational Study Based on Secondary Data) is an observational, longitudinal cohort study using data from electronic health records or claims data sources in Japan, Sweden, the United Kingdom, and the United States. Adults with a first hHF discharge between 2018 and 2022 were included. The 1-year event rates per 100 patient-years (ERs) for death and rehospitalizations (with a primary diagnosis of heart failure (HF), chronic kidney disease [CKD], myocardial infarction, stroke, or peripheral artery disease) were calculated. Hospital health care costs were cumulatively summarized. Cumulative GDMT use was assessed using Kaplan-Meier estimates. RESULTS: Of 263,525 patients, 28% died within the first year post-hHF (ER: 28.4 [95% CI: 27.0-29.9]). Rehospitalizations were mainly driven by HF (ER: 13.6 [95% CI: 9.8-17.4]) and CKD (ER: 4.5 [95% CI: 3.6-5.3]), whereas the ERs for myocardial infarction, stroke, and peripheral artery disease were lower. Health care costs were predominantly driven by HF and CKD. Between 2020 and 2022, use of renin-angiotensin system inhibitors, sacubitril/valsartan, beta-blockers, and mineralocorticoid receptor antagonists changed little, whereas uptake of sodium-glucose cotransporter-2 inhibitors increased 2- to 7-fold. CONCLUSIONS: Incident post-hHF rehospitalization risks and costs were high, and GDMT use changed little in the year following discharge, highlighting the need to consider earlier and greater implementation of GDMT to manage risks and reduce costs.

RESUMO

Heart failure (HF) remains one of the most common causes of hospitalization and mortality among Polish patients. The position of the Section of Cardiovascular Pharmacotherapy presents the currently applicable options for pharmacological treatment of HF based on the latest European and American guidelines from 2021-2022 in relation to Polish healthcare conditions. Treatment of HF varies depending on its clinical presentation (acute/chronic) or left ventricular ejection fraction. Initial treatment of symptomatic patients with features of volume overload is based on diuretics, especially loop drugs. Treatment aimed at reducing mortality and hospitalization should include drugs blocking the renin-angiotensin-aldosterone system, preferably angiotensin receptor antagonist/neprilysin inhibitor, i.e. sacubitril/valsartan, selected beta-blockers (no class effect - options include bisoprolol, metoprolol succinate, or vasodilatory beta-blockers - carvedilol and nebivolol), mineralocorticoid receptor antagonist, and sodium-glucose cotransporter type 2 inhibitor (flozin), constituting the 4 pillars of pharmacotherapy. Their effectiveness has been confirmed in numerous prospective randomized trials. The current HF treatment strategy is based on the fastest possible implementation of all four mentioned classes of drugs due to their independent additive action. It is also important to individualize therapy according to comorbidities, blood pressure, resting heart rate, or the presence of arrhythmias. This article emphasizes the cardio- and nephroprotective role of flozins in HF therapy, regardless of ejection fraction value. We propose practical guidelines for the use of medicines, profile of adverse reactions, drug interactions, as well as pharmacoeconomic aspects. The principles of treatment with ivabradine, digoxin, vericiguat, iron supplementation, or antiplatelet and anticoagulant therapy are also discussed, along with recent novel drugs including omecamtiv mecarbil, tolvaptan, or coenzyme Q10 as well as progress in the prevention and treatment of hyperkalemia. Based on the latest recommendations, treatment regimens for different types of HF are discussed.

RESUMO

OBJECTIVES: This study aimed to estimate the financial and economic impact of sacubitril/valsartan compared with enalapril for the treatment and prevention of hospitalization/rehospitalization because of heart failure with reduced ejection fraction (HFrEF). METHODS: The budget impact analysis was guided by the Philippine Reference Case and ISPOR's Principles of Good Practice for Budget Impact Analysis. A government-funded healthcare payer perspective and a societal perspective were considered. Data collection was guided by the pathways of disease progression and care. Collection of costing data followed a bottom-up approach. The model was based on a Markov model used in a study in Thailand. RESULTS: Over the next 5 years, there will be 17 625 less hospitalizations (∼5.1% less than enalapril arm) and 7968 less cardiovascular-related deaths (∼7.0% less than enalapril arm). In 5 years, the total cost of treating patients with HFrEF with sacubitril/valsartan at current market coverage and annual growth conditions is ₱15.430 billion, which is ₱11.077 billion higher than fully treating with enalapril only. The total required additional investment with treatment of sacubitril/valsartan compared with the full enalapril arm are ₱407 million (at 30-day coverage), ₱800 million (at 60-day coverage), and ₱1.181 billion (at 90-day coverage). If hospitalizations costs alone are considered, only the 30-day coverage is cost-saving. If a societal perspective is considered, all options are cost-saving where at least ₱4.003 billion is saved by the economy. CONCLUSION: The initial investment required to treat patients with HFrEF with sacubitril/valsartan is high; nevertheless, the year-on-year cost deficit shrinks in favor of investing in sacubitril/valsartan treatment.

RESUMO

Background Out-of-pocket costs have significant implications for patients with heart failure and should ideally be incorporated into shared decision-making for clinical care. High out-of-pocket cost is one potential reason for the slow uptake of newer guideline-directed medical therapies for heart failure with reduced ejection fraction. This study aims to characterize patient-cardiologist discussions involving out-of-pocket costs associated with sacubitril/valsartan during the early postapproval period. Methods and Results We conducted content analysis on 222 deidentified transcripts of audio-recorded outpatient encounters taking place between 2015 and 2018 in which cardiologists (n=16) and their patients discussed whether to initiate, continue, or discontinue sacubitril/valsartan. In the 222 included encounters, 100 (45%) contained discussions about cost. Cost was discussed in a variety of contexts: when sacubitril/valsartan was initiated, not initiated, continued, and discontinued. Of the 97 cost conversations analyzed, the majority involved isolated discussions about insurance coverage (64/97 encounters; 66%) and few addressed specific out-of-pocket costs or affordability (28/97 encounters; 29%). Discussion of free samples of sacubitril/valsartan was common (52/97 encounters; 54%), often with no discussion of a longer-term plan for addressing cost. Conclusions Although cost conversations were somewhat common in patient-cardiologist encounters in which sacubitril/valsartan was discussed, these conversations were generally superficial, rarely addressing affordability or cost-value judgments. Cardiologists frequently provided patients with a course of free sacubitril/valsartan samples without a plan to address the cost after the samples ran out.

RESUMO

BACKGROUND AND OBJECTIVES: Sacubitril/valsartan has shown effectiveness in reducing hospitalization compared with valsartan in HFpEF patients with heart failure with preserved ejection fraction (HFpEF). We aimed to investigate the cost effectiveness of sacubitril/valsartan as an alternative to valsartan in Chinese patients with heart failure with HFpEF. METHODS: A Markov model was built to investigate the cost effectiveness of sacubitril/valsartan as an alternative to valsartan in Chinese patients with HFpEF, from the healthcare system perspective. The time horizon was a lifetime, with a cycle length of 1 month. Costs were obtained from local information or published papers, discounted at a rate of 0.05 for future costs. The transition probability and utility were based on other studies. The primary outcome of the study was the incremental cost-effectiveness ratio (ICER). Sacubitril/valsartan was considered cost effective if the ICER obtained was lower than the willingness-to-pay threshold of US dollars (US$) 12,551.5 per quality-adjusted life-year (QALY). One-way and probabilistic sensitivity analyses, as well as scenario analysis, were performed to test robustness. RESULTS: Over a lifetime simulation, a 73-year-old Chinese patient with HFpEF could gain 6.44 QALYs (9.15 life-years) if sacubitril/valsartan plus standard treatment was administered, and 6.37 QALYs (9.07 life-years) if valsartan plus standard treatment was prescribed. The corresponding costs in both groups were US$12,471 and US$8663, respectively. The ICER was US$49,019/QALY (US$46,610/life-year), higher than the willingness-to-pay threshold. Sensitivity analyses and scenario analysis showed that our results were robust. CONCLUSION: Adding sacubitril/valsartan to standard treatment as an alternative to valsartan for the treatment of HFpEF resulted in more effectiveness but higher costs. Sacubitril/valsartan was likely to not be cost effective in Chinese patients with HFpEF. The cost of sacubitril/valsartan needs to reduce to 34% of its current price to be cost effective in this population. Studies based on real-world data are needed to confirm our conclusions.

RESUMO

BACKGROUND: Nebivolol and valsartan (VAL) in combination with each other successfully control blood pressure and improve hypertension patient outcomes. OBJECTIVE: To develop and validate innovative, simple, and sustainable spectrophotometric methods for the simultaneous analysis of nebivolol and valsartan. METHOD: The new modified difference amplitude modulation (MD-AM) method uses only unified regression equation and does not require any resolution techniques. Other different approaches were also applied for the determination of the same mixture including univariate and multivariate spectrophotometric methods. The multivariate methods were PLS and PCR, whereas the univariate methods were derivative ratio (DD1), ratio difference (RD), constant center (CC), constant center spectrum subtraction (CC-SS), constant value coupled with amplitude difference (CV-AD), advanced concentration value (ACV), and amplitude difference (AD). The proposed methods use a green solvent; thus, the environmental impact of the presented procedures was evaluated qualitatively and quantitatively using six well-known evaluation tools. RESULTS: All methods were applied successfully for the analysis of the studied drugs in their bulk powder, pharmaceutical dosage form Byvalson®, and in vitro release at intestinal pH (7.4) using a USP dissolution tester. Results obtained were compared statistically with the reported method and with each other using a one-way ANOVA statistical test, and no significant differences were found. CONCLUSIONS: All green and white analytical chemistry evaluation tools results confirm the safety, sustainability, and cost-effectiveness of the approaches, indicating that the methods are regarded green and sustainable. Results were agreeable, encouraging their applicability in quality control laboratories for dosage form and making these methods an eco-friendly substitute for the analysis of this combined dosage form and for evaluating the dissolution profile. HIGHLIGHTS: For the first time, a severely overlapped spectrum was determined using a unified regression equation without the need of extended part or zero contribution regions by the novel method MD-AM. The proposed methods are the first study of in vitro dissolution profiling of nebivolol hydrochloride (NEB) and VAL and the first sustainable and green methods applied without compromising the analytical criteria.

RESUMO

This research presents the occurrence and fate of 121 contaminants of emerging concern (CECs) in an urban aquifer polluted by river recharge through a data-base modelling. Afterwards, risk quotients (RQs) are computed to determine the risk posed by CECs to human health. To this end, groundwater and river water samples were collected in four campaigns conducted from February to May 2021. Results show that 46 CECs are ubiquitous in groundwater and their concentrations vary several orders of magnitude, ranging from below the limit of quantification to 44.5·103 ng/L for iopamidol. Transformation products (TPs) are usually detected at lower concentrations than those of the parent substances but there are some exceptions (i.e., fipronil sulphide, fipronil sulfone and O-desmethylvenlafaxine). River concentrations are higher than those detected in groundwater for some CECs, indicating the occurrence of natural attenuation processes when river water infiltrates the aquifer. A data-based advection-reaction modelling is proposed and tested for ca. 40 substances with detection frequencies higher than 90%. It provides useful quantitative information regarding the dynamic behaviour of the variables monitored, expressed in terms of characteristic length, entropy and synchronized state contribution. Finally, risk quotients (RQs) are used to assess the human health risk posed by the ubiquitous CECs in groundwater. Most CECs do not pose any risk to the different life stages considered, as the RQs evaluated are lower than 0.01. However, the pharmaceuticals valsartan and its TP valsartan acid show RQs higher than 1, indicating that these substances might be harmful to human beings.

RESUMO

Sacubitril/Valsartan (Sac-Val) has improved clinical prognosis in patients affected by heart failure (HF) with reduced ejection fraction (HFrEF). Comorbidities have a crucial impact on clinical presentation and prognosis in HF patients. Cognitive impairment (CoI) and Depression are a very common comorbidity in patients with HF and is widely recognized as a specific determinant of chronic disability, and HF patients with poor physical functional performance in Short physical performance battery (SPPB) showed a worse prognosis. The aim of the present study was to evaluate the potential effects of Sac-Val on functional, humoral, and cognitive aspects, evaluated by performing comprehensive geriatric assessment (CGA), in a cohort of elderly HFrEF. We studied 61 patients (51 men and 10 women, mean age 76.4 ± 5.1 years) suffering from HFrEF. After 6 months follow-up, we observed a significant improvement in humoral and functional parameters of CGA, renal function, NTpro-BNP levels and echocardiographic parameters. In the whole population, multivariate analysis shows that changes of Cardiac Index, NT-proBNP and Respiratory rate contributed for 26.0%, 9.7% and 4.8% to GDS variability, respectively, and the whole model accounted for a 41.1% of GDS variation; moreover changes of Global longitudinal strain, estimated glomerular filtration rate, Cardiac Index and BMI contributed for 23.9%, 11.7%, 5.4% and 4.0% to SPPB variability, respectively, and the whole model accounted for a 45% of SPPB variation. This represents the first real-world study carried out in an elderly population suffering from chronic HFrEF with numerous comorbidities, in which treatment with Sac-Val for 6 months induced important improvements in clinical, humoral, hemodynamic, and functional outcomes, without adverse effects on cognitive performance.

RESUMO

OBJECTIVES: To summarize cost-effectiveness (CE) evidence of sacubitril/valsartan for the treatment of heart failure (HF) patients with reduced ejection fraction (HFrEF). The impact of different modeling approaches and parameters on the CE results is also described. METHODS: We conducted a systematic literature review using multiple databases: Embase®; MEDLINE®; MEDLINE®-In Process; NIHR CRD database including DARE, NHS EED, and HTA databases; and the Cost Effectiveness Analysis registry. We also reviewed HTA countries' websites to identify CE reports of sacubitril/valsartan, published up to 25-July-2021. Articles published in English as full-texts, conference-abstracts, or HTA reports were included. RESULTS: We included 44 CE models [39 from 37 publications (22 full-texts; 15 conference-abstracts) and 5 HTAs; Europe, n = 20; North and South Americas, n = 14; Asia and Australia, n = 10]. Most models adopted a Markov structure with constant transition probabilities of events (n = 27) or a mix of Markov and regression-based models (n = 16), with variations in structural assumptions and chosen parameters. Study authors concluded sacubitril/valsartan to be a cost-effective therapy in 37/41 models in chronic HFrEF patients and 2/3 models in hospitalized patients stabilized after an acute decompensation for HF. CE models showing sacubitril/valsartan not to be a cost-effective treatment generally modeled a shorter time horizon. Effect of sacubitril/valsartan on cardiovascular and all-cause mortality, cost, duration of effect and time horizon was the main model drivers. CONCLUSIONS: Most evidence indicated sacubitril/valsartan is cost-effective in HFrEF. The use of a lifetime horizon is recommended in future models as HF is a chronic disease. Data on the CE of sacubitril/valsartan in the inpatient setting were limited and further research is warranted.

RESUMO

Objectives: The goal of this study was to compare cost-effectiveness of sacubitril/valsartan with angiotensin-converting enzyme (ACE) inhibitors for treating chronic heart failure patients with reduced ejection fraction (HFrEF) from the published articles and explore the methodology applied in the studies. Methods: Systematic research was conducted in February 2021 using PubMed, Cochrane, and EBSCO. A combination of MeSH terms of "cost-effectiveness analysis," "heart failure with reduced ejection fraction," "sacubitril valsartan," and "angiotensin converting enzyme inhibitor" was employed. The review selected for articles published in the last five years in English. Results: A total of 15 studies were included in this review. We found that these studies had been conducted in 12 different countries. The United States had the greatest number of publications (5), followed by the Netherlands (2). The study method most used was the Markov decision model (73%). Almost all studies produced ICERs and QALYs that were numerically high. Conclusions: The use of sacubitril/valsartan associates with longer life expectancy and incremental cost-effectiveness ratio than angiotensin-converting enzyme inhibitors.
