RESUMO

OBJECTIVES: Recovery from sexual trauma can be complex and multi-faceted. Most current psychological treatment protocols for trauma use a cognitive model of post-traumatic stress disorder (PTSD). However, sexual trauma may include specific complexities beyond that of a cognitive model of PTSD, such as relational factors. The distress experienced after sexual abuse may involve variables not exclusive to a PTSD model. Compassion focused therapy (CFT) is an approach that incorporates evolutionary, relational and social perspectives. This study explored the relationships between variables associated with CFT, PTSD and distress in survivors of sexual abuse to determine the role of CFT-related variables. METHODS: 155 adults who had experienced sexual abuse or any unwanted sexual experience at any point in their lives completed online questionnaires pertaining to various CFT variables (self-compassion, receiving compassion from others, having a fear of compassion from others, having a fear of compassion from the self, shame and self-criticism) and questionnaires measuring global distress as the outcome of sexual abuse and PTSD symptoms. RESULTS: An exploratory model involving CFT-related variables explained significantly more of the variance (4.4%) in global distress than PTSD symptomology alone. Self-criticism was found to be the variable with significant contribution. CONCLUSIONS: That CFT treatments, targeting self-criticism, should be developed alongside the standard cognitive model of PTSD based treatments for survivors of sexual abuse was supported. Future research may explore experimental designs utilizing CFT in this population, as well as further investigations on the roles of these specific CFT variables.

RESUMO

The financial desirability of dollar/time investments in postbaccalaureate healthcare professional education is needed. We therefore compared postbaccalaureate educational costs and career earnings for nurse anesthetists, eight other advanced degree, nonphysician professions, and 14 physician specialties with internal rate of return (IRR) and net present value (NPV) analysis. The IRR and NPV integrated educational costs (tuition, finance charges, lost salary opportunity costs), and career earnings using U.S. Bureau of Labor and Medscape 2022 Physician Compensation Report data. Costs were discounted to 2022 U.S. real dollars using the 3.97% 50-year, U.S. average inflation rate. Annual IRRs for educational investment were 1) hospital CEOs = 48.8%; 2) managed care finance directors = 48.2%; 3) Doctors of Nurse Anesthesia Practice = 26.0%; 4) specialist physicians = 20.3%; 5) primary care physicians = 19.2%; 6) Doctors of Physical Therapy = 18.8%; 7) healthcare attorneys = 18.4%; 8) Doctors of Dental Surgery (dentists) = 18.1%; 9) Doctors of Pharmacy = 17.2%; and 10) Advanced Nurse Practitioners = 10.8%. Considering the educational money/time invested for career monetary returns, the financial desirability of nurse anesthetist and nonphysician, healthcare executive education exceeded that of physicians. Lifetime earnings for nurse anesthetists exceeded those of Doctors of Dental Surgery (Doctors of Dental Medicine), Doctors of Pharmacy, Doctors of Physical Therapy, managed care MBAs, biomedical engineers, healthcare attorneys, and Advanced Nurse Practitioners.

RESUMO

BACKGROUND: Little is known about the skills involved in clinical formulation. The individual case formulation (ICF) approach, based on functional analysis, employs clinical descriptions that are theory-free and depicts formulations constructed according to a set of basic conventions. AIMS: We report a test of whether this method could be taught and if the quality of the resulting diagrams could be reliably rated. METHOD: Participants (n=40) participated in a training course in formulation. A draft rating scale was refined in the course of rating formulation diagrams and basic inter-rater reliability established. RESULTS: Results of the study support further development of the ICF approach.

RESUMO

Cerebrospinal fluid (CSF) is an aqueous solution responsible for nutrient delivery and waste removal for the central nervous system (CNS). The three-layer meningeal coverings of the CNS support CSF flow. Peripheral nerves have an analogous three-layer covering consisting of the epineurium, perineurium, and endoneurium. Peripheral axons, located in the inner endoneurium, are bathed in "endoneurial fluid" similar to CSF but of undefined origin. CSF flow in the peripheral nervous system has not been demonstrated. Here we show CSF flow extends beyond the CNS to peripheral nerves in a contiguous flowing system. Utilizing gold nanoparticles, we identified that CSF is continuous with the endoneurial fluid and reveal the endoneurial space as the likely site of CSF flow in the periphery. Nanogold distribution along entire peripheral nerves and within their axoplasm suggests CSF plays a role in nutrient delivery and waste clearance, fundamental aspects of peripheral nerve health and disease. One Sentence Summary: Cerebrospinal fluid unites the nervous system by extending beyond the central nervous system into peripheral nerves.

RESUMO

PURPOSE: To quantify the cost-utility ratio of the ranibizumab Port Delivery System (PDS; SUSVIMO) versus intravitreal ranibizumab injections for treating neovascular age-related macular degeneration (nAMD) based upon Archway Phase 3 Trial data. DESIGN: Cost-utility analysis. SUBJECTS: Archway Phase 3 Clinical Trial nAMD participants previously responsive to anti-VEGF therapy were randomized 3:2. Two hundred forty received PDS refills q 24 weeks and 162 received ranibizumab injections. METHODS: Ophthalmic patient, time tradeoff utilities, direct medical and societal cost perspectives, 12-year, 1-year, and 5-year timelines, United States 2022 real dollars, and a 3% annual discount rate were employed. Utilities were adjusted for nAMD conversion in fellow eyes during the 12-year, mean participant life expectancy. Premature death associated with severe vision loss was integrated as per the population-based Salisbury Eye Evaluation Study. MAIN OUTCOME MEASURES: Quality-adjusted life-year (QALY) accruals, costs, and incremental and average cost-utility ratios in $/QALY (dollars expended per QALY gained). RESULTS: Versus no therapy, the 1-year PDS QALY gain was 0.0156 (6.8%) versus 0.0063 (0.82%) for intravitreal injections (P < 0.001), whereas the respective 12-year QALY gains were 1.714 (28%) and 1.639 (26.8%) (P = 0.99). One-year direct PDS ophthalmic costs totaled $21 825 with 2 ranibizumab fills, whereas ranibizumab injection therapy totaled $18 405 with 11.8 injections. The 1-year incremental PDS $/QALY versus injections was cost effective at $75 497/QALY. Five-year PDS therapy was not incrementally cost effective at $304 108/QALY, nor was the 12-year therapy at $761 646/QALY. Average 12-year cost-utility ratios were $78 773/QALY for the PDS and $47 917/QALY for injection therapy. Adding -$476 442 12-year offsetting societal costs netted $314 521 to society per PDS participant versus $370 958 per participant for injection therapy. CONCLUSIONS: Ranibizumab PDS therapy was not incrementally cost effective versus ranibizumab injection therapy at 12 or 5 years but was at 1 year. Injection therapy had a more favorable 12-year average cost-utility ratio. Vision gain was the major determinant of participant value gain and was the same for both interventions. Both interventions were highly cost effective utilizing average cost-utility analysis with the societal cost perspective.

RESUMO

Proatheris superciliaris, the lowland swamp viper, has a limited distribution along lakeshores and rivers in Malawi, Southern Tanzania, and central Mozambique. Its venom is known to be procoagulant. Only five P. superciliaris bites have been reported, all inflicted by captive snakes, and none was fatal. Here we present a case of sudden death following a bite by Proatheris superciliaris in rural Malawi that cannot be attributed to envenoming. A healthy 32-year-old woman was planting rice in a flooded rice paddy field when she suddenly told her sister in a quiet voice that she had been bitten by a snake. She then collapsed face-upwards into the ankle-deep water. She remained motionless while her sister and uncle carried her out of the rice paddy onto dry land a few meters away. The victim did not regain consciousness. Her uncle heard one exhalation but no further breathing. The snake responsible was killed by a friend. Although the venom of this species can cause life-threatening coagulopathy, this woman's death occurred too rapidly to be attributable to envenoming. Only two explanations seem plausible: anaphylaxis, or vasovagal shock triggered by fear. In the present case, the victim died within minutes of the bite, closely observed by her anxious relatives, but showed no features of anaphylaxis. In Malawi, as in much of sub-Saharan Africa, many people are reportedly terrified of snakes, believing that bites by almost any species can cause rapid death. In this case, death occurred less than 2 min after a bite from Proatheris superciliaris. We believe that the cause of death was most likely a severe vasovagal attack, in response to the fear and pain of the snakebite that triggered vasodilatation, bradycardia, and hypotension leading to cardiac arrest.

RESUMO

A 2017 service evaluation identified a lack of information and knowledge among patients who were referred on to early phase oncology clinical trials (Hood, 2020). An educational booklet was developed to improve patients' knowledge and experience. To build upon this work, a patient co-designed website was developed. This study examined the impact, if any, of a patient co-designed educational intervention within the clinical pathway for patients who are referred for an early phase oncology clinical trial at an experimental cancer medicine centre (ECMC). AIMS: 1. To understand the experiences of patients who have been referred to an ECMC for an early phase clinical trial pre- and post-intervention. 2. To investigate if the intervention reduced anxiety levels in newly referred patients. METHOD: A convergent mixed-methods design was used in this study, to collect quantitative and qualitative data in parallel. OUTCOMES: This study examined the experiences of advanced cancer patients who attended their initial research outpatient appointment to discuss the possibility of taking part in an early phase clinical trial and the impact of an educational resource.

RESUMO

INTRODUCTION: Oral administration of zeaxanthin (Zx) 20 mg daily in patients with unilateral neovascular age-related macular degeneration (nAMD) treated with triple therapy (photodynamic therapy/intravitreal bevacizumab/intravitreal dexamethasone) reduced fellow-eye 2-year nAMD incidence from 23 to 6% (p = 0.02) in a prior clinical trial. We questioned the long-term benefit and thus analyzed case-control 5-year patient data of trial participants and additional participants with 5-year follow-up, also performing cost-utility and cost-benefit analyses. METHODS: Consecutive, unilateral nAMD patient outcomes for those taking 20 mg Zx supplementation orally for ≥ 5 years were compared with the Comparison of AMD Treatments Trials (CATT) 5-year historical controls for fellow-eye nAMD conversion. Eleven-year mean life expectancy, cost-utility and cost-benefit models were undertaken employing a 3% discount rate and 2020 US real dollars. RESULTS: Among 227 consecutive patients with nAMD/Zx-supplementation, 202 (90%) had 5-year follow-up. The fellow-eye nAMD 5-year conversion incidence using a Kaplan-Meier cumulative event estimate was 22% (49/227), versus 48% (167/348) with CATT control data (p < 0.0001). An 11-year cost-utility model with estimates for years 6-11 demonstrated a 0.42 (7.7%) QALY (quality-adjusted life-year) gain, including 3 months of life saved per patient due to decreased nAMD fellow-eye conversion. This yielded a direct ophthalmic medical cost perspective, incremental cost-utility ratio (CUR) of -$576/QALY and a societal cost perspective CUR of -$125,071/QALY. Zx supplementation for all 2020 US unilateral nAMD cases would have theoretically saved society, primarily patients, $6.0 billion over 11 years, a 1531% return on investment (ROI), or 31.3% annual ROI, on Zx costs. CONCLUSIONS: Oral zeaxanthin supplementation for unilateral nAMD patients appears to decrease fellow-eye long-term incidence and is cost-effective and financially rewarding. It is dominant vs. no supplementation in patients presenting with unilateral nAMD. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT01527435.

RESUMO

Imagery rescripting (ImRs) is a therapy technique that, unlike traditional re-living techniques, focuses less on exposure and verbal challenging of cognitions and instead encourages patients to directly transform the intrusive imagery to change the depicted course of events in a more desired direction. However, a comprehensive account of how and in what circumstances ImRs brings about therapeutic change is required if treatment is to be optimised, and this is yet to be developed. The present study reports on the development of a coding scheme of ImRs psychotherapy elements identified in the literature as potential ImRs mechanisms. The codes were assessed in relation to short-term outcomes of 27 individuals undergoing ImRs for post-traumatic stress disorder. The timing of the change in the image, degree of activation of the new image and associated cognitive, emotional and physiological processes, self-guided rescripting, rescript believability, narrative coherence and cognitive and emotional shift were identified as being related to symptom change and so are potentially important factors for the re-scripting process.

RESUMO

Disparity in hospice use threatens optimal quality of life during the final stage of life while American Indians/Alaska Natives may not be aware of hospice benefits. Our established Blackfeet members and Montana State University collaborative team conducted a modified Duke End-of-Life Care Survey (8 sections with 60 questions) to assess a baseline end-of-life values, beliefs, and attitudes of Blackfeet individuals. In this manuscript, we present the results of 3 sections with 28 questions: Preference of Care; Beliefs About Dying, Truth Telling, and Advance Care Planning; and Hospice Care by examining overall and generational differences. Most participants (n = 92) chose quality of life over quantity of life with using various devices if they had an incurable disease (54-82%), would want to know if they were dying (92%) or had cancer (89%), but had not thought or talked about their preference of end-of-life care (30% and 35% respectively). The results portray understandable cultural context as well as generational differences with personal variability. While an affirmative shift towards hospice was emerging, dissemination of accurate hospice information would benefit people in the partner community. In conclusion, an individual-centered approach-understanding individual need first-may be the most appropriate and effective strategy to promote hospice information and its use.

RESUMO

OBJECTIVE: Time trade-off (TTO) utility analysis quantifies the quality of life associated with best-seeing-eye (BSE) vision. We compared the patient quality of life associated with unilateral and bilateral no light perception (NLP) with that of a control cohort without NLP. DESIGN: Cross-sectional interviews using a validated, reliable TTO vision utility analysis instrument. PARTICIPANTS: A total of 1598 consecutive ophthalmology patients from the authors' practices. METHODS: Patient records were reviewed in a case-control fashion The utilities of participants with unilateral or bilateral NLP vision were compared with those from patients without NLP vision. RESULTS: Among 99 NLP patients, 93 (94%) had unilateral NLP and 6 (6%) had bilateral NLP, for a total of 105 NLP eyes. Multiple regression analysis demonstrated the highest correlation between utility and BSE acuity (p = 0.001), with no correlation with age, ophthalmic disease, time of vision loss, race, or education. Mean unilateral NLP utility ranged from 0.55 in the counting fingers to light perception subcohort to 0.80 in the 20/20-20/25 subcohort. The 6-person bilateral NLP subcohort had a 0.54 utility. The 99-patient NLP cohort mean utility was 0.69, a 55% quality-of-life decrease versus a BSE vision-matched 0.80 in 1499 non-NLP patients (p < 0.001). CONCLUSIONS: TTO utility in unilateral NLP patients correlated with BSE vision at a lower utility than in patients with matched BSE vision without fellow-eye NLP. Decreased unilateral NLP patient quality of life should be considered in cost-utility analysis and clinical management. Bilateral NLP patient utility (0.54) was slightly less than that (0.55) in blind unilateral NLP patients with fellow-eye counting fingers to light perception vision, suggesting that more study is needed.

RESUMO

Taboo perception on talking about death and dying among American Indians/Alaska Natives is prevalent. This suppressive value makes hospice introduction difficult, leading hospice disparity. Working together by using a community-based participatory research approach over a decade, we conducted a 6-hour workshop including information sharing and group activities. The purpose of the study was to investigate the community readiness for end-of-life knowledge by conducting a public workshop. We used pre- and post-workshop surveys with Likert-type responses to five questions to assess the effect of workshop in end-of-life knowledge. Thirty individuals participated the workshop; 80% of them reported their knowledge increase on at least one question. While the survey had concerns, positive participant responses indicated readiness and appropriateness to use workshops to increase end-of-life knowledge.

RESUMO

PURPOSE: Utilities are preference-based estimates, typically ranging from 1.00 (normal health) to 0.00 (death), that quantify the quality-of-life improvement associated with a health care intervention. In conjunction with length-of-life gain, depending on the intervention, they measure total interventional value gain in quality-adjusted life years that can be integrated with costs in cost-utility analysis. We believed it relevant to ascertain whether race was a differentiating factor confounding utilities related to vision. METHODS: An analysis of cross-sectional data obtained from consecutive Black and White ophthalmic outpatients from the Wills Eye Hospital (Philadelphia, PA.) practices who participated in a long-standing time trade-off (TTO) vision utility study from 1999 to 2016 was undertaken. Each participant was interviewed by a researcher using a previously validated and reliable TTO vision utility acquisition instrument and assigned to 1 of 5 vision categories according to acuity in the best-seeing eye. Utility outcomes were compared using both the 2-sided t test and the Mann-Whitney U test. RESULTS: Eleven hundred and twenty-five consecutive patients able to successfully answer the questions were included. For vision of 20/200-20/800, White/Black mean vision utilities were, respectively, 0.58/0.59 (p = 0.84); for vision of 20/70-20/100, they were, respectively, 0.72/0.70 (p = 0.85); for vision of 20/50-20/60, they were, respectively, 0.78/0.79 (p = 0.86); for vision of 20/25-20/50, they were, respectively, 0.84/0.88 (p = 0.16); and for vision of 20/20, they were, respectively, 0.91/0.90 (p = 0.43). CONCLUSIONS: TTO vision utilities in Black and White ophthalmic patient cohorts were alike at various levels of visual acuity. This suggests a similar quality of life and that TTO vision utilities used in cost-utility analysis do not require adjustment for race in Black and White ophthalmic populations in the US.

RESUMO

BACKGROUND: A key clinical issue is how to maximise the belief change central to cognitive therapy. Physiological arousal is a key internal cue confirming threat beliefs in anxiety disorders. Deeper extinction of anxiety may occur if catastrophizing responses to physiological arousal are inhibited prior to joint exposure with external phobic stimuli. The aim of the study was to test whether increasing physiological arousal using exercise increases the benefits of behavioural tests. METHODS: Sixty individuals with a fear of heights had one session of VR cognitive treatment. They were randomised to have the treatment either with periods of intense physical exercise (cycling at 80% of maximum heart rate) prior to exposures or without. Linear mixed effects models were used to check the manipulation and test the primary hypothesis of a group difference in degree of conviction in the phobic threat belief. RESULTS: Heart rate was significantly higher in the exercise group throughout compared with the control group. Both groups showed significant reductions in threat beliefs after the VR treatment (d = 1.0, p < 0.001) but there was no significant group difference (d = 0.1, p = 0.56). DISCUSSION: An increase in physiological arousal achieved via exercise did not enhance cognitive change in beliefs about feared stimuli.

RESUMO

IMPORTANCE: Select research methods in cost-utility analysis (incremental cost-effectiveness analysis) might potentially bias against patient value (quality-adjusted life-year [QALY]) gain and cost-effectiveness associated with common ophthalmic interventions in disabled, elderly, and African American populations. OBJECTIVE: To ascertain whether using nonpatient vision utilities and/or a maximum limit model constraining vision utility gain to the systemic comorbidity utility level biases against ophthalmic cost-utility outcomes. DESIGN, SETTING, AND PARTICIPANTS: This economic evaluation predominantly used data from the Center for Value-Based Medicine database to perform preference-based comparative effectiveness and cost-utility analyses for cataract surgery and intravitreal ranibizumab therapy for neovascular age-related macular degeneration (NVAMD) using vision utilities acquired from patients with ophthalmic disease (ophthalmic patient utilities) and from surrogate individuals (nonophthalmic patient vision utilities) with and without integrating systemic comorbidity utility limits on vision utility gain. Ophthalmic patient data were collected from January 1, 2000, to December 31, 2016, and analyzed from April 1 to July 1, 2020. INTERVENTIONS: Cost-utility analysis with 3% discount rate in 2018 US dollars. MAIN OUTCOMES AND MEASURES: QALY gains and dollars expended per QALY gain (the cost-utility ratio). RESULTS: A total of 309 participants in the nonophthalmic patient cohort and 505 patients in the ophthalmic patient cohort were included. A reference case of first-eye cataract surgery using ophthalmic patient vision utilities and no systemic comorbidity utility limits yielded a 2.574 (34.2%) QALY gain vs observation. Substituting nonophthalmic patient utilities resulted in a 1.502 (15.5%) QALY gain, whereas using the 0.76 patient systemic comorbidity utility to limit cataract surgery vision utility gain yielded a 1.337 (17.8%) QALY gain. Using both nonophthalmic patient utilities and systemic comorbidity utility limits yielded a 0.839 (8.7%) QALY gain. The substitutions decreased cataract surgery cost-effectiveness by 71.3% (95% CI, 70.6%-72.1%) for nonophthalmic patient utilities, 92.5% (95% CI, 51.9%-133.1%) for patient systemic comorbidity utility, and 206.8% (95% CI, 202.6%-211.2%) for both. The NVAMD ranibizumab therapy reference case yielded a 1.339 (26.1%) QALY gain. Similar substitutions resulted in QALY gains of 1.164 (22.7%) for nonophthalmic patient utilities while reducing cost-effectiveness by 16.4%, 1.001 (19.5%) for systematic-limiting comorbidity utility while reducing cost-effectiveness by 33.8%, and 0.971 (18.9%) for both while reducing cost-effectiveness by 37.9%. CONCLUSIONS AND RELEVANCE: Using nonophthalmic patient vision utilities and/or the maximum limit model of limiting patient utility gains to the population systemic comorbidity utility level resulted in large decreases in patient value (QALY) gain and cost-effectiveness for common ophthalmic interventions. Ophthalmologists should realize these phenomena and consider correcting the potential discrimination against disabled, elderly, and African American populations. This negative potential bias could theoretically result in beneficial intervention denial, less research dollars, curbed therapeutic advances, and decreased interventional reimbursement.

RESUMO

OBJECTIVE: To estimate perceptions of quality-of-life (QOL) associated with vision loss in youths under age 21 and compare them with adult general community perceptions and those of ophthalmic patients with vision loss. DESIGN: Cross-sectional, time tradeoff (TTO), utility analysis. PARTICIPANTS: Consecutive youths aged 13-20 years who agreed to participate in the study. METHODS: Vision utilities were acquired from adolescents asked to estimate the QOL associated with 3 vision scenarios using a validated, reliable, interviewer-administered TTO utility instrument. The scenarios modeled included: (i) mild vision loss (20/40-20/60), (ii) moderate vision loss (20/70-20/100), and (iii) severe vision loss (≤20/200). Results were compared with utilities previously gathered from the adult general community and from vision-impaired patients with acuity loss to the level of the modeled scenarios. RESULTS: Mean TTO vision utilities were: scenario 1: youths (0.96) versus patients (0.79) (p < 0.0001); scenario 2: youths (0.88) versus patients (0.72) (p < 0.0001); scenario 3: (analysis of variance p < 0.0001) Tukey's Honestly Significant Difference Test, youths (0.79) versus patients (0.60) (p < 0.01), youths (0.79) versus adult general community (0.85) (p < 0.01), adult general community (0.85) versus patients (0.60) (p < 0.01). CONCLUSIONS: Adolescents underestimated the effects of mild, moderate, and severe vision loss upon QOL referent to patients with actual vision loss (p < 0.0001), and thus are not good patient surrogates for utilities used in cost-utility analysis. Nonetheless, youth estimates were closer to those of patients with vision loss than were adult general community estimates. These findings emphasize the importance of using patient utilities in cost-utility analysis.

RESUMO

PURPOSE: To perform a societal cost-benefit analysis comparing intravitreal bevacizumab (Avastin), ranibizumab (Lucentis), and aflibercept (Eylea) monotherapies for treating neovascular age-related macular degeneration (NVAMD). DESIGN: Cost-benefit analysis. METHODS: Center for Value-Based Medicine using published clinical trial and Medicare data. PATIENT POPULATION: 168,400 estimated 2018 U.S. patients with new-onset NVAMD. Procedure(s): cost-benefit analysis using 2018 U.S. real dollars. OUTCOME MEASUREMENTS: 11-year direct ophthalmic medical costs expended for bevacizumab, ranibizumab, and aflibercept monotherapies were compared with ophthalmic and nonophthalmic direct medical, direct nonmedical, and indirect medical (productivity) costs saved by the therapies. RESULTS: Bevacizumab monotherapy had an individual, 11-year $14,772 treatment cost and net $357,680 societal return (11-year 2,421% return on investment [ROI]). Ranibizumab therapy cost $106,582 and returned $265,870 to society (249% ROI), whereas aflibercept treatment cost $61,811 and returned $310,611 to society (503% ROI). The 2018 NVAMD overall treatment cohort, 11-year net societal gain was $28.5 billion to patients and insurers, with $24.2 billion (84.9%) coming from bevacizumab therapy, $0.7 billion (2.5%) from ranibizumab therapy, and $3.6 billion (12.6%) from aflibercept therapy. Substituting bevacizumab for ranibizumab and aflibercept in the 2018 new-onset NVAMD patients would save an estimated $1.343 billion over 11 years. Vascular endothelial growth factor-inhibitor (VEGF-I) therapy in 2018 should contribute $12.2 billion to the Gross Domestic Product over 11 years. Late treatment would decrease this by 78% to $2.7 billion. CONCLUSIONS: Intravitreal NVAMD bevacizumab, ranibizumab and aflibercept monotherapies accrue considerable financial, ROIs to patients and insurers as they increase national wealth.
