Single-session catheter-directed lysis using adjunctive clot fragmentation with power pulse spray only is a fast, safe, and effective option for acute pulmonary embolism

OBJECTIVE

Single-session, catheter-directed thrombolysis (CDT) with adjunctive power pulse spray (PPS) only, without thrombectomy, was evaluated for its safety and effectiveness. We performed a single-center, retrospective analysis of prospectively collected data.

METHODS

Patients with high-risk or intermediate-risk pulmonary embolism (PE) who met the inclusion criteria and underwent a single session of CDT-PPS were included in the study. The primary outcomes assessed were technical and clinical success and major adverse events. Secondary outcomes included effectiveness based on pre- and postintervention clinical examination, radiographic findings, and reversal of right ventricular dysfunction at 48 hours and 4 weeks after discharge on echocardiography and computed tomography pulmonary angiography. The length of stay in the intensive care unit and overall admission were also analyzed. A return to premorbid exercise tolerance was evaluated at 12 months after the procedure.

RESULTS

Between May 2016 and January 2023, 104 patients at the Wollongong Hospital were diagnosed with high- or intermediate-risk PE and underwent CDT-PPS. Of the 104 patients, 49 (47%) were considered to have high-risk PE and 55 (53%) intermediate-risk PE. Eleven patients (11%) had absolute contraindications and 49 patients (47%) had relative contraindications to systemic thrombolysis. Technical success was achieved in 102 patients (98%). Survival was 99% at 48 hours, 96% at 4 weeks, and 91% at 12 months. At 4 weeks, echocardiography showed 98% of patients had no evidence of right heart dysfunction, and computed tomography pulmonary angiography showed complete resolution of PE in 72%. There were no major adverse events at 48 hours. The median intensive care unit length of stay was 1 day, and the overall length of stay was 6 days. At 12 months, 96% had returned to their premorbid status.

CONCLUSIONS

The CDT-PPS technique is fast, safe, and effective in the treatment of high- and intermediate-risk PE, even in patients with a high bleeding risk, and should be considered as first-line management when the skills and resources are available. Further multicenter prospective studies are needed to corroborate these results.

Evidence-Based Update on Transcatheter Therapies for Pulmonary Embolism

PURPOSE OF REVIEW

Pulmonary embolism (PE) remains a leading cause of cardiovascular morbidity and mortality. Multiple new therapies are in development and under study to improve our contemporary care of patients with PE. We review and compare here these novel therapeutics and technologies.

RECENT FINDINGS

Multiple novel therapeutic devices have been developed and are under active study. This work has advanced the care of patients with intermediate and high-risk PE. Novel therapies are improving care of complex PE patients. These have inspired large multicenter international randomized controlled trials that are actively recruiting patients to advance the care of PE. These studies will work towards advancing guidelines for clinical care of patients with PE.

Integrating Pharmacomechanical Treatments for Pulmonary Embolism Management within a Hub-and-Spoke System in the Swiss Ticino Region

The Swiss Ticino regional pulmonary embolism response team (PERT) features direct access to various pharmacomechanical PE management options within a hub/spoke system, by integrating evidence, guidelines' recommendations and personal experiences. This system involves a collaborative management of patients among the hospitals distributed throughout the region, which refer selected intermediate-high or high PE patients to a second-level hub center, located in Lugano at Cardiocentro Ticino, belonging to the Ente Ospedaliero Cantonale (EOC). The hub provides 24/7 catheterization laboratory activation for catheter-based intervention (CBI), surgical embolectomy and/or a mechanical support system such as extracorporeal membrane oxygenation (ECMO). The hub hosts PE patients after percutaneous or surgical intervention in two intensive care units, one specialized in cardiovascular anesthesiology, to be preferred for patients without relevant comorbidities or with hemodynamic instability and one specialized in post-surgical care, to be preferred for PE patients after trauma or surgery or with relevant comorbidities, such as cancer. From April 2022 to December 2023, a total of 65 patients were referred to the hub for CBI, including ultrasound-assisted catheter-directed thrombolysis (USAT) or large-bore aspiration intervention. No patient received ECMO or underwent surgical embolectomy.

Anti-factor Xa as the preferred assay to monitor heparin for the treatment of pulmonary embolism

INTRODUCTION

The mainstay of acute pulmonary embolism (PE) treatment is anticoagulation. Timely anticoagulation correlates with decreased PE-associated mortality, but the ability to achieve a therapeutic activated partial thromboplastin time (aPTT) with unfractionated heparin (UFH) remains limited. Although some institutions have switched to a more accurate and reproducible test to assess for heparin's effectiveness, the anti-factor Xa (antiXa) assay, data correlating a timely therapeutic antiXa to PE-associated clinical outcomes remains scarce. We evaluated time to a therapeutic antiXa using intravenous heparin after PE response team (PERT) activation and assessed clinical outcomes including bleeding and recurrent thromboembolic events.

METHODS

This was a retrospective cohort study at NYU Langone Health. All adult patients ≥18 years with a confirmed PE started on IV UFH with >2 antiXa levels were included. Patients were excluded if they received thrombolysis or alternative anticoagulation. The primary endpoint was the time to a therapeutic antiXa level of 0.3-0.7 units/mL. Secondary outcomes included recurrent thromboembolism, bleeding and PE-associated mortality within 3 months.

RESULTS

A total of 330 patients with a PERT consult were identified with 192 patients included. The majority of PEs were classified as sub massive (64.6%) with 87% of patients receiving a bolus of 80 units/kg of UFH prior to starting an infusion at 18 units/kg/hour. The median time to the first therapeutic antiXa was 9.13 hours with 93% of the cohort sustaining therapeutic anticoagulation at 48 hours. Recurrent thromboembolism, bleeding and mortality occurred in 1%, 5% and 6.2%, respectively. Upon univariate analysis, a first antiXa <0.3 units/ml was associated with an increased risk of mortality [27.78% (5/18) vs 8.05% (14/174), p = 0.021].

CONCLUSION

We observed a low incidence of recurrent thromboembolism or PE-associated mortality utilizing an antiXa titrated UFH protocol. The use of an antiXa based heparin assay to guide heparin dosing and monitoring allows for timely and sustained therapeutic anticoagulation for treatment of PE.

Pulmonary embolism response teams. A description of the first 36-month Australian experience

BACKGROUND

High/intermediate-risk pulmonary embolism (PE) confers increased risk of cardiovascular morbidity and mortality. International guidelines recommend the formation of a PE response team (PERT) for PE management because of the complexity of risk stratification and emerging treatment options. However, there are currently no available Australian data regarding outcomes of PE managed through a PERT.

AIMS

To analyse the clinical and outcome data of patients from an Australian centre with high/intermediate-risk PE requiring PERT-guided management.

METHODS

We performed a retrospective observational study of 75 consecutive patients with high/intermediate-risk PE who had PERT involvement, between August 2018 and July 2021. We recorded clinical and interventional data at the time of PERT and assessed patient outcomes up to 30 days from PERT initiation. We used unpaired t tests to compare right to left ventricular (RV/LV) ratios by computed tomography criteria or transthoracic echocardiogram (TTE) at baseline and after interventions.

RESULTS

Data were available for 74 patients. Initial computed tomography pulmonary angiography RV/LV ratio was increased at 1.65 ± 0.5 and decreased to 1.30 ± 0.29 following PERT-guided interventions (P < 0.001). TTE RV/LV ratio also decreased following PERT-guided management (1.09 ± 0.19 vs 0.93 ± 0.17; P < 0.001). 20% of patients had any bleeding complication, but two-thirds were mild, not requiring intervention. All-cause mortality was 6.8%, and all occurred within the first 7 days of admission.

CONCLUSION

The PERT model is feasible in a large Australian centre in managing complex and time-critical PE. Our data demonstrate outcomes comparable with existing published international PERT data. However, successful implementation at other Australian institutions may require adequate centre-specific resource availability and the presence of multispeciality input.

Glycemic Variability Assessment in Newly Treated Exocrine Pancreatic Insufficiency With Type 1 Diabetes

BACKGROUND

Thirty-nine percent of people with type 1 diabetes may have lowered pancreatic elastase levels, correlated with exocrine pancreatic insufficiency (EPI or PEI). EPI is treated with oral supplementation of pancreatic enzymes. Little is known about the glycemic impact of pancreatic enzyme replacement therapy (PERT) in people with diabetes. This article demonstrates a method of assessing glycemic variability (GV), glycemic outcomes, and other changes in an individual with type 1 diabetes using open-source automated insulin delivery (AID).

METHOD

Macronutrient, PERT intake, and EPI-related symptoms were self-tracked; diabetes data were collected automatically via an open-source AID system. Diabetes data were uploaded via Nightscout to Open Humans and downloaded for analysis alongside self-tracked data (food, PERT). Glycemic outcomes, macronutrients, PERT dosing, and a variety of GV metrics following meals were evaluated for one month before and one month after PERT commencement. Breakfast was assessed independently across both time periods.

RESULTS

In an n = 1 individual using an open-source AID, time in range was already above goal and improved further after PERT commencement. Glucose rate of change and excursions >180 mg/dL were reduced; mean high blood glucose index was reduced overall and more so specifically at breakfast following PERT commencement.

CONCLUSIONS

GV can aid in assessing response to new-onset medications, as was demonstrated in this article for n = 1 individual with type 1 diabetes (using an open-source AID) after commencing PERT for newly identified EPI. GV may be useful for evaluating the efficacy of new-onset medications for people with insulin-requiring diabetes.

Pancreatic enzyme prescription following ivacaftor licensing: A retrospective analysis of the US and UK cystic fibrosis registries

BACKGROUND

Relieving gastrointestinal symptoms is a research priority in cystic fibrosis. Emerging evidence highlights effects of cystic fibrosis transmembrane conductance regulator (CFTR) modulators on gastrointestinal function, including pancreatic sufficiency. This study explores ivacaftor licensing and treatment on recorded pancreatic enzyme replacement therapy (PERT) prescription in the US and UK CF registries.

METHODS

Retrospective longitudinal registry study of recorded pancreatic PERT use between 2008 and 2017. Interrupted time series analysis in propensity-matched cohorts estimated annual change and step change according to ivacaftor eligibility before and after licensing year, 2012. Generalised estimating equations assessed adjusted risk of PERT use in individuals treated with ivacaftor after 2012 compared to untreated individuals.

RESULTS

In the US CF registry, the difference in annual change in prevalence of PERT use post-2012 between eligible cases and ineligible controls was -5.0 per 1000 people/year (95 %CI -7.6; -2.3, p = 0.001). The step change and annual change in prevalence of PERT use in eligible cases was not significantly different to controls in the UK CF registry. Relative to the relationship in 2013, ivacaftor treatment in the US CF registry was associated with a lower adjusted risk ratio of PERT use compared to untreated individuals by 2016 (0.97, 95 %CI 0.96; 0.99), which was not observed in the UK CF registry.

CONCLUSIONS

Licensing of ivacaftor was followed by a lower prevalence of PERT use in the eligible US population compared to pre-licensing period, as well as lower risk of PERT use in those who received treatment. Inconsistencies in US and UK CF registries were observed.

Exocrine Pancreatic Insufficiency Dosing Guidelines for Pancreatic Enzyme Replacement Therapy Vary Widely Across Disease Types

BACKGROUND

Pancreatic enzyme replacement therapy (PERT) is the standard treatment for exocrine pancreatic insufficiency (EPI). However, many individuals are inadequately treated, with gaps in clinical dosing, guidelines, and tools to aid individual titration.

METHODS

A systematic review identified research and guidelines on PERT dosing recommendations across conditions, systematically reviewing and synthesizing total PERT intake, meal/snack guidelines, and changes over time to provide an up-to-date look at the most common doses used in studies and guidelines.

RESULTS

This review of 257 articles found wide variability in PERT dosing guidelines within and across conditions. Many patients with EPI are underdosed, with guidelines differing globally and by disease type, and clinician prescribing may also play a role. The most common dosing guidelines focus on starting doses at 40,000-50,000 units of lipase/meal with increases of up to two to three times this amount before pursuing additive therapies. Guidelines and studies typically focus only on fat digestion, and comparison by total daily dose shows underdosing is common. Most PERT studies are on safety and efficacy rather than optimal titration.

CONCLUSION

The current guidelines for PERT in EPI demonstrate substantial variability in dosing recommendations, both within and across disease types. This variation highlights the need for further research to optimize PERT dosing and improve patient outcomes. Healthcare providers should consider individualizing PERT dosing based on nutritional status and response to therapy, ensuring regular follow-up with patients for dose titrations with consideration that most guidelines are framed as initial doses rather than upper limits.

Implementing a Pediatric Pulmonary Embolism Response Team Model: An Institutional Experience

Pulmonary embolism is increasing in prevalence among pediatric patients; although still rare, it can create a significant risk for morbidity and death within the pediatric patient population. Pulmonary embolism presents in various ways depending on the patient, the size of the embolism, and the comorbidities. Treatment decisions are often driven by the severity of the presentation and hemodynamic effects; severe presentations require more invasive and aggressive treatment. We describe the development and implementation of a pediatric pulmonary embolism response team designed to facilitate rapid, multidisciplinary, data-driven treatment decisions and management.

Designing a phase-III time-to-event clinical trial using a modified sample size formula and Poisson-Gamma model for subject accrual that accounts for the lag in site initiation using the PERT distribution

A priori estimation of sample size and subject accrual in multi-site, time-to-event clinical trials is often challenging. Such trials are powered based on the number of events needed to detect a clinically significant difference. Sample size based on number of events relates to the expected duration of observation time for each subject. Temporal patterns in site initiation and subject enrollment ultimately affect when subjects can be accrued into the study. Lag times are common as the site start-up process optimizes, resulting in delays that may curtail observational follow-up and therefore undermine power. The proposed method introduces a Program Evaluation and Review Technique (PERT) model into the sample size estimation which accounts for the lag in site start-up. Additionally, a PERT model is introduced into a Poisson-Gamma subject accrual model to predict the quantity of study sites needed. The introduction of the PERT model provides greater flexibility in both a priori power assessment and planning the number of sites, as it specifically allows for the inclusion of anticipated delays in site start-up time. This model results in minimal power loss even when PERT distribution inputs are misspecified compared to the traditional assumption of simultaneous start-up for all sites. Together these updated formulations for sample size and subject accrual models offer an improved method for designing a multi-site time-to-event clinical trial that accounts for a flexible site start-up process.

Exocrine Pancreatic Insufficiency in Children - Challenges in Management

Cystic fibrosis (CF) is the leading etiology for exocrine pancreatic insufficiency (EPI) in children, followed by chronic pancreatitis, Shwachman-Diamond syndrome, and other genetic disorders. Management of EPI in children poses several unique challenges such as difficulties in early recognition, lack of widespread availability of diagnostic tests and limited number of pediatric-specific pancreatic centers. Pancreatic enzyme replacement therapy is the cornerstone of EPI management and in young children difficulties in administering pancreatic enzymes are frequently encountered. Patients with EPI also should be screened for fat-soluble vitamin deficiencies and receive appropriate supplementation. Among disorders with EPI in children, CF is the relatively well-studied condition, and most management recommendations for EPI in children come from expert consensus and conventional practice guidelines. The impact of EPI can be greater in children given their high metabolic demands and rapid growth. Early diagnosis and aggressive management of EPI prevent consequences of complications such as malnutrition, fat-soluble vitamin deficiencies, and poor bone health and improve outcomes. Management by multi-disciplinary team is the key to success.

Temporal trends in the utilization of advanced therapies among patients with acute pulmonary embolism: insights from a national database

There is a paucity of data regarding the contemporary temporal trends in the adoption of advanced pulmonary embolism (PE) therapies in the United States as well as the parallel trends in outcomes of patients with acute PE. Therefore, we queried the Nationwide Readmissions Database (years 2016-2020) to report the temporal trends in utilization of advanced PE therapies. Our final analysis included 920 770 hospitalizations with acute PE. We demonstrated an increase in the proportion of patients diagnosed with high-risk PE during the study years. Overall, there was an increase in the use of advanced PE therapies, which was mainly due to the increase in the utilization of systemic thrombolytics, and catheter-directed therapies. Also, extracorporeal membrane oxygenation cannulation showed an incremental increase over the study years. The use of inferior vena cava filter has declined, while the use of surgical embolectomy did not change during the study years. The use of advanced therapies has increased among urban teaching, but not among urban non-teaching hospitals. During the study years, there was no change in unadjusted or adjusted in-hospital mortality rates among patients with acute PE, while the 90-day unplanned readmission rate has declined.

Pancreatic Enzyme Replacement and Nutritional Support With nab-Paclitaxel-based First-Line Chemotherapy Regimens in Metastatic Pancreatic Cancer

BACKGROUND

At diagnosis, more than 80% of patients with pancreatic cancer (PC) suffer from significant weight loss due to malnutrition which is a major concern for patient management, and this may negatively impact treatment outcomes and patient prognosis.

PATIENTS AND METHODS

We performed an observational, retrospective study on patients with metastatic PC (mPC) undergoing first-line chemotherapy with nab-Paclitaxel containing schedules and receiving or not receiving nutritional support (NS) and pancreatic enzyme replacement therapy (PERT) to investigate their relevance in this setting.

RESULTS

We observed that PERT and ancillary dietary interventions are related to longer overall survival (OS; median: 16.5 vs. 7.5 months, P < .001) and have a significant, independent, prognostic impact for better outcomes (P = .013), independently from the therapeutic regimen. Furthermore, PERT and NS prevented weight loss during chemotherapy and obtained an improvement of nutritional parameters such as phase angle and free-fat mass index, after 3 months of anticancer treatment. Consistently, the positive impact on OS correlated also with the prevention of Karnofsky performance status deterioration and a lower incidence of maldigestion-related symptoms.

CONCLUSIONS

Our data suggest that an early and well-conducted NS in patients with mPC may impact on survival and preserve performance status, thus improving quality of life.

Survey of Pancreatic Enzyme Replacement Therapy Dosing Experiences in Adults with Exocrine Pancreatic Insufficiency

OBJECTIVES

Pancreatic enzyme replacement therapy (PERT) is essential for treating exocrine pancreatic insufficiency (EPI), a condition where the pancreas does not produce adequate enzymes for digestion. This study delves into the real-world experiences of individuals with EPI regarding their PERT usage.

METHODS

A study was executed using a tailored survey targeting individuals with EPI. Quantitative data analysis assessed factors such as age, duration of EPI, elastase levels, choice of PERT, perceived effectiveness of titration, and the time taken for effective titration.

RESULTS

The study comprised 111 participants, predominantly female (93%) and hailing from North America (79%). Of these, 36.7% had been diagnosed with EPI for 3 or more years. A significant 72% felt they were not consistently consuming adequate enzymes, with only 22% believing their intake was sufficient. There were 44 participants (42%) still in the process of adjusting their enzyme doses. In contrast, 17 participants (16%) took a few weeks, 21 (20%) a few months, 11 (10%) over six months, 10 (9%) more than a year, and 3 (3%) several years for dose adjustment. Regarding enzyme titration advice, 30 participants (29%) received vague guidance, while 22 (21%) found the advice beneficial.

CONCLUSIONS

This study underscores the pressing need for enhanced PERT dosing guidance. The insights gleaned spotlight the prevalent undertreatment across the entire EPI demographic, including in those with lesser-studied co-conditions.

Catheter-directed mechanical thrombectomy in a patient with high-risk pulmonary embolism complicated by out-of-hospital cardiac arrest: a case report

Background

Pulmonary embolism (PE) is common, and it is the third leading cause of cardiovascular death. The management of patients with high-risk PE generally consists of systemic thrombolysis; however, surgical or catheter-directed treatment (CDT) can be considered in selected cases.

Case summary

A 78-year-old female patient presenting with acute severe dyspnoea develops out-of-hospital cardiac arrest (OHCA). She was admitted with return of spontaneous circulation and a critical haemodynamic state upon arrival to the catheterization laboratory with an estimated no-flow time of 1 min and low-flow time of 52 min. An acute pulmonary angiogram reveals massive PE. After a PE response team conference, the patient was not found eligible for extracorporeal membrane oxygenation, surgery, or thrombolysis. The patient was treated with catheter-directed mechanical thrombectomy 129 min after first medical contact. The patient recovered and was discharged without any neurological deficits.

Discussion

Catheter-directed mechanical thrombectomy was a successful treatment in a patient with OHCA secondary to high-risk PE, where thrombolysis and surgical interventions were considered contraindicated. This case underlines the future perspectives of CDT and also that a multidisciplinary team approach may benefit patients with high-risk PE.

Nutrition in children with exocrine pancreatic insufficiency

Exocrine pancreatic insufficiency (EPI) is a condition defined as pancreatic loss of exocrine function, including decreased digestive enzymes and bicarbonate secretion, which leads to maldigestion and malabsorption of nutrients. It is a common complication in many pancreatic disorders. If left undiagnosed, EPI can cause poor digestion of food, chronic diarrhea, severe malnutrition and related complications. Nutritional status and fat-soluble vitamins should be carefully assessed and monitored in patients with EPI. Early diagnosis of EPI is clinically important for appropriate nutritional support and initiating pancreatic enzyme replacement therapy (PERT) which could significantly improve patient outcomes. The evaluation of nutritional status and related unique management in children with EPI will be discussed in this review.

Pancreatic Enzyme Replacement Therapy in Cystic Fibrosis

While typically considered a pulmonary disease, cystic fibrosis patients develop significant nutritional complications and comorbidities, especially those who are pancreatic insufficient. Clinicians must have a high suspicion for cystic fibrosis among patients with clinical symptoms of pancreatic insufficiency, and pancreatic enzymatic replacement therapy (PERT) must be urgently initiated. PERT presents a myriad of considerations for patients and their supporting dieticians and clinicians, including types of administration, therapy failures, and complications.

Concise Review of the Rationale for Pulmonary Embolism Treatment and Endovascular Device Therapies

In the ever-changing landscape of device therapy for pulmonary embolism, it is important to understand the rationale behind the ongoing explosion in the development of new device therapies. There needs to be an in-depth understanding of risk stratification in pulmonary embolism and indications for therapy. Selecting the ideal device for a particular pulmonary embolism subset remains elusive and poorly defined. Knowledge of the risks, bene-fits, capabilities, and potential limitations of each device is crucial.

Relationship Between the Self-Concept of Children and Their Ability to Recognize Emotions in Others

The aim of this study was to assess the relationship between the self-concept of children and their ability to recognize emotions in others from facial expressions. It is hypothesized that children use their self-representations to interpret depictions of emotion in others and that higher self-concepts might be associated with earlier development of emotion recognition skills. A total of 54 children aged between 5 and 11 years participated in this study. Self-concept was assessed in all children using the Piers-Harris Self-Concept Scale for Children (Piers-Harris 2). To assess emotion recognition, a computerized instrument, the Penn Emotion Recognition Task (PERT), was applied. Despite the small sample of children, results show clear statistical effects. It is shown that emotion recognition ability is directly correlated with self-concept for intellectual/school status. The ability to correctly identify emotions from facial expressions is affected by general self-concept, intellectual/school status, and stimulus features of gender, intensity, and emotion. Further analysis shows that the general self-concept of children particularly affects the ability to identify happy faces. Children with a higher intellectual status score recognize happiness and neutral faces more easily. We concluded that the self-concept in children relates to the ability to recognize emotions in others, particularly positive emotions. These findings provide some support to the simulation theory of social cognition, where children use their own self-representations to interpret mental states in others. The effect of the self-concept for intellectual status on emotion recognition might also indicate that intellectual abilities act as a mediator between self-concept and emotion recognition, but further studies are needed.

Resting heart rate as a surrogate for improvement in intermediate risk pulmonary embolus patients?

BACKGROUND

Pulmonary embolism (PE) response teams (PERT) have been developed to improve in-hospital mortality. Identifying intermediate risk PE patients that will progress despite anticoagulation is difficult, especially because outcomes with modern anticoagulation are quite good.

OBJECTIVE

The primary aim of this study was to evaluate the rate of anticoagulation failure (new deep vein thrombosis or PE, right ventricular failure resulting in shock, cardiac arrest, or PE-attributable death) in intermediate risk PE patients managed by PERT. The secondary objective was to determine whether there was a significant decrease in heart rate 24 h after initiation of anticoagulation in intermediate risk PE.

METHODS

This was a retrospective observational study of patients treated for acute intermediate risk PE at the University of Rochester Medical Center who also had outpatient followup between November 2016-June 2019.

RESULTS

Ninety-two patients presented as intermediate-risk PE and had outpatient followup. Seventy-four patients were initially treated with anticoagulation. None of these patients failed anticoagulation. Of the eighteen intermediate risk patients that underwent advanced intervention, none failed anticoagulation first. There was significant decrease in resting heart rate 24 h after starting therapeutic anticoagulation, 107 beats/min vs 89 beats/min, p = 0.0001.

CONCLUSION

We did not observe anticoagulation failure in the management of acute, intermediate risk PE. Reductions in heart rate may reflect improvements in right ventricular function; we hypothesize that those whose heart rate does not fall may be optimal candidates for advanced intervention.

Low Bone Mineral Density and Risk for Osteoporotic Fractures in Patients with Chronic Pancreatitis

Introduction: Chronic pancreatitis (CP) can lead to malnutrition, an established risk factor for low bone mineral density (BMD) and fractures. This study aims to determine the prevalence of low BMD, assess fracture incidence and explore risk factors for fractures in patients with CP. Patients and methods: We performed a retrospective analysis of all patients treated for CP at Karolinska University Hospital between January 1999 and December 2020. Electronic medical records were retrieved to assess demographic, laboratory and clinical data. Patients subjected to dual-energy X-ray absorptiometry (DXA) were categorised as either low BMD or normal BMD. We investigated whether the rate of fractures, defined by chart review, differed between these groups using Cox regression, adjusting the model for age, sex and body mass index (BMI). Additional within-group survival analysis was conducted to identify potential risk factors. Results: DXA was performed in 23% of patients with definite CP. Some 118 patients were included in the final analysis. Low BMD was present in 63 (53.4%) patients. Mean age at CP diagnosis in the total cohort was 53.1 years and was significantly lower in patients with normal BMD than in patients with low BMD (45.5 vs. 59.8, p < 0.001). Significant differences were observed in smoking status and disease aetiology, i.e., a higher proportion of patients with low BMD were current or former smokers, with nicotine or alcohol being a more common cause of CP (p < 0.05). Total follow-up time was 898 person-years. Fractures were found in 33 (28.0%) patients: in 5 of 55 patients (16.7%) with normal DXA and in 28 of 63 patients (44.4%) with low BMD (adjusted hazard ratio = 3.4, 95% confidence interval (CI) = 1.2-9.6). Patients with at least 3 months of consecutive pancreatic enzyme replacement therapy (PERT) or vitamin D treatment had a longer median time to fracture after CP diagnosis. Conclusion: DXA was only performed in 23% of patients with definite CP in this study, indicating a low adherence to current European guidelines. A low BMD was found in 53.4% of patients with CP, and 44% of the patients with a low BMD experienced a fracture during follow-up. Moreover, the fracture rate in patients with low BMD increased compared to those with normal BMD.

Prospective Experience of Pulmonary Embolism Management and Outcomes

OBJECTIVE

We sought to evaluate the impact of pulmonary embolism (PE) response teams (PERTs) on all consecutive patients with PE.

BACKGROUND

Multidisciplinary PERTs have been promoted for the management and treatment of (PE); however, the impact of PERTs on clinical outcomes has not been prospectively evaluated.

METHODS

We prospectively studied 220 patients with computed tomography (CT)-confirmed PE between January, 2019 and August, 2019. Baseline characteristics, as well as medical, interventional, and operational care, were captured. The total population was divided into 2 groups, ie, those with PERT activation and those without PERT activation. PERT activation was left at the discretion of the primary team. Our primary outcome was 90-day composite endpoint (rate of readmission, major bleeds, and mortality). Using 2:1 propensity-matched and multivariable-adjusted Cox proportional hazard analyses, we examined the impact of PERT activation on primary outcome, treatment approach, and length of stay.

RESULTS

Of the total 220 patients, PERT was activated in 47 (21.4%). The PERT cohort, as compared with the non-PERT cohort, was more likely to present with dyspnea, syncope, lower systolic blood pressure, higher heart rate, higher respiratory rate, lower oxygen saturation, higher troponin levels, and higher right ventricular to left ventricular ratio. PERT activation was associated with increased use of advanced therapies (36.2% vs 1.2%; P<.001) and catheter-directed inventions (25.5% vs 0.6%; P<.001). In multivariable-adjusted analysis of propensity-matched cohorts, PERT activation was associated with lower 90-day outcomes (hazard ratio, 0.40; 95% confidence interval, 0.21-0.75; P<.01).

CONCLUSION

At our institution, PERT had a clinically significant impact on therapeutic strategies and 90-day outcomes in patients with PE.

Diagnosis and Treatment of Pulmonary Embolism During the Coronavirus Disease 2019 Pandemic: A Position Paper From the National PERT Consortium

The coexistence of coronavirus disease 2019 (COVID-19) and pulmonary embolism (PE), two life-threatening illnesses, in the same patient presents a unique challenge. Guidelines have delineated how best to diagnose and manage patients with PE. However, the unique aspects of COVID-19 confound both the diagnosis and treatment of PE, and therefore require modification of established algorithms. Important considerations include adjustment of diagnostic modalities, incorporation of the prothrombotic contribution of COVID-19, management of two critical cardiorespiratory illnesses in the same patient, and protecting patients and health-care workers while providing optimal care. The benefits of a team-based approach for decision-making and coordination of care, such as that offered by pulmonary embolism response teams (PERTs), have become more evident in this crisis. The importance of careful follow-up care also is underscored for patients with these two diseases with long-term effects. This position paper from the PERT Consortium specifically addresses issues related to the diagnosis and management of PE in patients with COVID-19.

Suboptimal care for chronic pancreatitis patients revealed by moderate to low adherence to the United European Gastroenterology evidence-based guidelines (HaPanEU): A Netherlands nationwide analysis

Background and objective

The 2016, United European Gastroenterology evidence-based guidelines for the diagnosis and therapy of chronic pancreatitis (HaPanEU) provided evidence-based recommendations for the management of chronic pancreatitis and allowed for the objective evaluation of the quality of care in several domains of disease management through assessment of guideline adherence. Therefore, the aim of this study is to evaluate the current level and the variety of care for chronic pancreatitis patients in the Netherlands using the HaPanEU guidelines as a reference standard. The majority of these patients were diagnosed before the publication of these guidelines. Therefore, in most patients, the results of the present study with respect to those recommendations regarding the diagnostic process of chronic pancreatitis represent guideline correspondence and not adherence.

Methods

A subgroup of patients from the Dutch nationwide chronic pancreatitis registry (CARE) was included in a retrospective cross-sectional observational cohort study. A total of 39 recommendations concerning the non-invasive management of chronic pancreatitis were appointed as quality indicators (QIs). Per patient, the number of relevant QIs was determined and guideline adherence was assessed. Data were analyzed to identify factors associated with guideline adherence.

Results

Overall, 97 patients with chronic pancreatitis from 11 hospitals were included. Per patient, a mean number of 26 relevant QIs was applicable, with an average adherence rate of 53%. In 45% of the patients, guideline adherence was less than 50%. The majority of suboptimal managed QIs concerned the management of chronic pancreatitis complications. Guideline adherence was not associated with hospital type, sex, age or etiology of pancreatitis.

Conclusion

In the Netherlands, adherence to the HaPanEU recommendations for the management of chronic pancreatitis is moderate to low for all non-invasive domains, which may indicate suboptimal care for these patients. Closer guideline adherence could improve the level of care and the clinical outcomes of these patients. A nationwide approach to increase awareness of the key guideline recommendations among clinicians and patients is needed.

Adoption of a dedicated multidisciplinary team is associated with improved survival in acute pulmonary embolism

Background

Acute pulmonary embolism remains a significant cause of mortality and morbidity worldwide. Benefit of recently developed multidisciplinary PE response teams (PERT) with higher utilization of advanced therapies has not been established.

Methods

To evaluate patient-centered outcomes and cost-effectiveness of a multidisciplinary PERT we performed a retrospective analysis of 554 patients with acute PE at the university of Virginia between July 2014 and June 2015 (pre-PERT era) and between April 2017 through October 2018 (PERT era). Six-month survival, hospital length-of-stay (LOS), type of PE therapy, and in-hospital bleeding were assessed upon collected data.

Results

317 consecutive patients were treated for acute PE during an 18-month period following institution of a multidisciplinary PE program; for 120 patients PERT was activated (PA), the remaining 197 patients with acute PE were considered as a separate, contemporary group (NPA). The historical, comparator cohort (PP) was composed of 237 patients. These 3 groups were similar in terms of baseline demographics, comorbidities and risk, as assessed by the Pulmonary Embolism Severity Index (PESI). Patients in the historical cohort demonstrated worsened survival when compared with patients treated during the PERT era. During the PERT era no statistically significant difference in survival was observed in the PA group when compared to the NPA group despite significantly higher severity of illness among PA patients. Hospital LOS was not different in the PA group when compared to either the NPA or PP group. Hospital costs did not differ among the 3 cohorts. 30-day re-admission rates were significantly lower during the PERT era. Rates of advanced therapies were significantly higher during the PERT era (9.1% vs. 2%) and were concentrated in the PA group (21.7% vs. 1.5%) without any significant rise in in-hospital bleeding complications.

Conclusions

At our institution, all-cause mortality in patients with acute PE has significantly and durably decreased with the adoption of a PERT program without incurring additional hospital costs or protracting hospital LOS. Our data suggest that the adoption of a multidisciplinary approach at some institutions may provide benefit to select patients with acute PE.

Value-based assessment of implementing a Pulmonary Embolism Response Team (PERT)

PERTs are a new, multidisciplinary approach to PE care. They were conceived to efficiently identify and risk stratify PE patients and standardize care delivery. More research needs to be conducted to assess the effects that PERTs have had on PE care. This study sought to determine the effects of a PERT on quality and overall value of care. This was a retrospective study of all patients 18 years of age or older who presented with a principal diagnosis of an acute PE based on available ICD codes from January 1, 2010 to December 31, 2018. Patients who did not have an imaging study, i.e., CTPA or ECHO, available were excluded. Patients were divided into pre- (before October 2015) and post-PERT eras (after October 2015) and stratified based on the presence of right heart strain/dysfunction on imaging. All quality outcomes were extracted from the EMR, and cost outcomes were provided by the financial department. 530 individuals (226 pre-PERT and 304 post-PERT) were identified for analysis. Quality outcomes improved between the eras; most notably in-hospital mortality decreased (16.5 vs. 9.6) and hospital LOS decreased (7.7 vs. 4.4) (p < 0.05). Total cost of care also decreased a statistically significant amount between the eras. The implementation of a PERT improved quality and cost of care, resulting in improved value. We hypothesize that this may be due to more timely identification and risk stratification leading to earlier interventions and streamlined decision making, but further research is required to validate these findings in larger cohorts.

Use of a mobile application for self-management of pancreatic enzyme replacement therapy is associated with improved gastro-intestinal related quality of life in children with Cystic Fibrosis

BACKGROUND

Most patients with cystic fibrosis (CF) suffer from pancreatic insufficiency (PI), leading to fat malabsorption, malnutrition, abdominal discomfort and impaired growth. Pancreatic enzyme replacement therapy (PERT) is effective, but evidence based guidelines for dose adjustment are lacking. A mobile app for self-management of PERT was developed in the context of the HORIZON 2020 project MyCyFAPP. It contains an algorithm to calculate individual PERT-doses for optimal fat digestion, based on in vitro and in vivo studies carried out in the same project. In addition, the app includes a symptoms diary, educational material, and it is linked to a web tool allowing health care professionals to evaluate patient's data and provide feedback.

METHODS

A 6-month open label prospective multicenter interventional clinical trial was performed to assess effects of using the app on gastro-intestinal related quality of life (GI QOL), measured by the CF-PedsQL-GI (shortened, CF specific version of the Pediatric Quality of Life Inventory, Gastrointestinal Symptoms Module).

RESULTS

One hundred and seventy-one patients with CF and PI between 2 and 18 years were recruited at 6 European CF centers. Self-reported CF-PedsQL-GI improved significantly from month 0 (M0) (84.3, 76.4-90.3) to month 6 (M6) (89.4, 80.35-93.5) (p< 0.0001). Similar improvements were reported by parents. Lower baseline CF-PedsQL-GI was associated with a greater improvement at M6 (p < 0.001).

CONCLUSIONS

The results suggest that the MyCyFAPP may improve GI QOL for children with CF. This tool may help patients to improve self-management of PERT, especially those with considerable GI symptoms.

Future perspectives in catheter-based treatment of pulmonary embolism

Pulmonary embolism is the third commonest cause of cardiovascular death globally. The majority of such patients present with low-risk features and can be managed with simple anticoagulation; however, a large group of patients exhibit evidence of right ventricular dysfunction on echocardiography or CT at the time of presentation and these patients are at risk of early haemodynamic compromise, particularly in those with abnormal cardiac biomarkers. Catheter-directed thrombolysis has been proposed as a treatment-strategy for patients with pulmonary embolism with evidence of acute right ventricular dysfunction. We review the current technologies in mainstream use, the evidence base in support of their use and discuss future research requirements in this area.

The implementation of a pulmonary embolism response team in the management of intermediate- or high-risk pulmonary embolism

BACKGROUND

Massive and submassive pulmonary embolism (PE) can be life-threatening. Treatment options include anticoagulation, fibrinolysis, catheter-directed or open surgical thrombus removal, and extracorporeal membrane oxygenation. With increasing patient complexity and advanced therapeutic options, the approach to optimal care for patients with intermediate- to high-risk PE is not clearly established. Multidisciplinary, rapid response teams can optimize risk stratification and expedite management. A PE response team (PERT) composed of specialists from cardiology, vascular surgery, emergency medicine, pulmonary and critical care, interventional radiology, cardiac surgery, hospital medicine, and pharmacy was created at our institution. The team is tasked with evaluating and treating patients with massive and submassive PE by use of a risk stratification and treatment algorithm. We describe our initial experience with this approach.

METHODS

The records of patients treated by the PERT since inception in October 2015 through May 2017 were reviewed (intervention group). The diagnoses codes of the PERT patients were retrieved from the Vizient database. A retrospective control cohort group was created using these specific diagnoses and a matching set of demographics (age, sex), Medicare Severity Diagnosis Related Group, admission severity of illness, and admission risk of mortality. Statistical analysis was performed using the Fisher exact test, the Pearson χ² statistic, Student t-test, and Cochran-Cox approximation. P < .05 was considered significant.

RESULTS

During the time interval, 77 patients with massive or submassive PE were treated by PERT activation; 992 patients included in the control group were treated at the discretion of an attending physician without use of the algorithm from October 2013 to 2016. Both groups had similar demographics, similar distribution of risk of mortality and severity of illness, and similar average Medicare Severity Diagnosis Related Group weighting. There was no statistically significant difference in the mortality rate between the two groups. The PERT group had significantly lower intensive care unit stay and overall length of stay. No difference was seen in direct cost between the two groups despite higher use of interventional treatment modalities in the PERT group.

CONCLUSIONS

In our institution, assembly of a dedicated team to treat patients with massive or submassive PE according to a clinical algorithm resulted in expedited treatment and reduced variation of care. Intensive care unit stay and overall length of stay were reduced by this approach, with no impact on direct cost despite the use of advanced modalities of treatment. We believe that this paradigm can be of potential value in other disease entities, particularly when multiple disciplines are involved.

Changes in treatment and outcomes after creation of a pulmonary embolism response team (PERT), a 10-year analysis

Multidisciplinary pulmonary embolism response teams (PERTs) are being implemented to improve care of patients with life-threatening PE. We sought to determine how the creation of PERT affects treatment and outcomes of patients with serious PE. A pre- and post-intervention study was performed using an interrupted time series design, to compare patients with PE before (2006-2012) and after (2012-2016) implementation of PERT at a university hospital. T-tests, Chi square tests and logistic regression were used to compare outcomes, and multivariable regression were used to adjust for differences in PE severity. Two-sided p-value < 0.05 was considered significant. For the interrupted time-series analysis, data was divided into mutually exclusive 6-month time periods (11 pre- and 7 post-PERT). To examine changes in treatment and outcomes associated with PERT, slopes and change points were compared pre- and post-PERT. Two-hundred and twelve pre-PERT and 228 post-PERT patients were analyzed. Patient demographics were generally similar, though pre-PERT, PE were more likely to be low-risk (37% vs. 19%) while post-PERT, PE were more likely to be submassive (32% vs. 49%). More patients underwent catheter directed therapy (1% vs. 14%, p = < 0.0001) or any advanced therapy (19 [9%] vs. 44 [19%], p = 0.002) post PERT. Interrupted time series analysis demonstrated that this increase was sudden and coincident with implementation of PERT, and most noticeable among patients with submassive PE. There were no differences in major bleeding or mortality pre- and post-PERT. While the use of advanced therapies, particularly catheter-directed therapies, increased after creation of PERT, especially among patients with submassive PE, there was no apparent increase in bleeding.

Treatment of submassive and massive pulmonary embolism: a clinical practice survey from the second annual meeting of the Pulmonary Embolism Response Team Consortium

There is a paucity of robust clinical trial data to guide the treatment of acute pulmonary embolism (PE) thus the clinical guidelines rely heavily on expert opinion. Pulmonary Embolism Response Teams (PERT) have been developed to streamline the care of patients with acute PE. We conducted a survey among 100 experts in the field of PE during the second annual meeting of the PERT Consortium. Respondents were queried with respect to their demographic information, clinical practice questions and clinical vignettes. Clinical practice questions were focused questions about the risk stratification and treatment of patients with acute submassive PE, anticoagulation strategies for patients receiving thrombolysis and the use of inferior vena cava filters. Clinical vignettes were designed to assess participants' preferred choice of treatment for a variety of commonly encountered clinical scenarios. Among physicians affiliated with a PERT, there is overall agreement with regards to the criteria used for risk classification of patients with PE and its application to patients in the provided clinical vignettes. In contrast, there is substantial variability in the treatment strategies of patients presenting with commonly encountered clinical scenarios. The results of this survey highlight the need for more clinical trial data along with accepted algorithms for treatment of acute PE. In the absence of this, PERTs can facilitate multidisciplinary discussions in order to standardize treatment and provide evidence-based therapies to patients with acute PE.

Pancreatic enzyme replacement therapy following surgery for pancreatic cancer: An exploration of patient self-management

BACKGROUND

For those diagnosed with pancreatic cancer, ill-addressed pancreatic exocrine insufficiency (PEI) following surgery can result in malnutrition related complications that may impact on predict mortality and morbidity. The use of pancreatic enzyme replacement therapy (PERT) is recommended and often demands a degree of patient self-management. Understanding more about how this treatment is managed is fundamental to optimising care.

OBJECTIVE

This study aimed to explore patient self-management of PERT following surgery for pancreatic cancer.

METHODS

Semi-structured interviews were conducted with nine participants. Eligible participants included adult patients who had undergone surgery for a malignancy in the pancreatic region and were prescribed PERT post-operatively. Inductive thematic analysis was used to analyse our findings.

RESULTS

Data analysis revealed three overarching themes; the role of professional support, factors influencing decisions to use PERT in symptom management and the challenges of socializing. The difficulties negotiated by participants were considerable as they struggled with the complexities of PERT. Symptom management and subsequently reported physical repercussions and undesirable social implications were problematic. Professional support was largely inconsistent and relinquished prematurely following discharge. Consequently, this impacted on how PERT was self-managed.

CONCLUSION

Enabling patients to appropriately self-manage PERT may lessen the post-treatment burden. Our findings suggest that support should continue throughout the recovery phase and should address the patient's 'self-management journey'. Intervention by healthcare professionals, such as a specialist dietitian is likely to be beneficial. Furthermore there are focal issues, primarily explicit education and appropriately timed information that require consideration by those developing and delivering services.

The Role of the Pulmonary Embolism Response Team: How to Build One, Who to Include, Scenarios, Organization, and Algorithms

Pulmonary embolism response teams (PERTs) are multidisciplinary response teams aimed at delivering a range of diagnostic and therapeutic modalities to patients with pulmonary embolism. These teams have gained traction on a national scale. However, despite sharing a common goal, individual PERT programs are quite individualized-varying in their methods of operation, team structures, and practice patterns. The tendency of such response teams is to become intensely structured, algorithmic, and inflexible. However, in their current form, PERT programs are quite the opposite. They are being creatively customized to meet the needs of the individual institution based on available resources, skills, personnel, and institutional goals. After a review of the essential core elements needed to create and operate a PERT team in any form, this article will discuss the more flexible feature development of the nascent PERT team. These include team planning, member composition, operational structure, benchmarking, market analysis, and rudimentary financial operations.

A primer on exocrine pancreatic insufficiency, fat malabsorption, and fatty acid abnormalities

Exocrine pancreatic insufficiency (EPI) is characterized by a deficiency of exocrine pancreatic enzymes, resulting in deficits in digestion of all macronutrients, with deficiencies in digestion of fats being the most clinically relevant. The leading cause of EPI is chronic pancreatitis. However, many other causes and conditions may be implicated, including cystic fibrosis, pancreatic duct obstruction, gastric and pancreatic surgery, diabetes mellitus and other conditions. Physical and biochemical causes of EPI include decreased production and secretion of lipase, increased lipase destruction, pancreatic duct obstruction, decreased lipase stimulation and degradation, as well as gastrointestinal motility disorders. EPI is largely diagnosed clinically, and is often identified by symptoms such as steatorrhea, weight loss, abdominal discomfort, and abdominal bloating. Lifestyle modifications (eg, smoking cessation, limiting or avoiding alcoholic drinks, and reducing dietary fat intake) and exogenous pancreatic enzyme supplements are commonly used to help restore normal digestion and absorption of dietary nutrients in patients with EPI.

Guidance for supplemental enteral nutrition across patient populations

Enteral nutrition is preferred over parenteral nutrition as a result of the greater safety of enteral nutrition therapy and comparative convenience. A wide variety of enteral nutrition products have been developed, including disease-specific products to help manage the nutritional needs of patients with kidney failure, liver failure, lung disease, diabetes, and other conditions. An assessment of each patient's nutritional needs and digestive function should be conducted prior to initiation of enteral nutrition therapy. Other considerations in determining the appropriate route and method of enteral nutrition administration include the time and nursing involvement required for administration, potential complications of medication administration, and concerns related to pancreatic dysfunction in certain groups. Tailored guidelines and treatment considerations are reviewed in this manuscript the application of enteral nutrition in various patient populations.

Options for addressing exocrine pancreatic insufficiency in patients receiving enteral nutrition supplementation

Patients with exocrine pancreatic insufficiency (EPI) have suboptimal secretion of pancreatic digestive enzymes and experience a range of clinical symptoms related to the malabsorption of fat. In patients with EPI unable to meet their nutritional requirements, enteral nutrition (EN) support is used to augment nutritional status. In addition to protein and carbohydrate, EN formulas contain fats as a calorie source, as well as vitamins and minerals to help prevent nutritional deficiencies related to malabsorption. Semielemental enteral nutrition formulas are advantageous as they contain hydrolyzed protein, shorter chain carbohydrates, and may contain medium chain triglycerides as a fat source. However, severely pancreatic insufficient patients may be unable to absorb complex long-chain triglycerides provided by EN formulas due to insufficient pancreatic lipase; replacement pancreatic enzyme products are recommended for these patients. Currently, none of the FDA-approved pancreatic enzyme replacement therapy (PERT) products are indicated for use in patients receiving enteral nutrition and administration of enzymes by mixing into enteral nutrition formula is not supported by guidelines as this route is associated with risks. RELiZORB (immobilized lipase) is a novel in-line digestive cartridge that has been designed to address the unmet need for PERT in patients receiving enteral nutrition. RELiZORB efficacy and compatibility with a range of commercially available polymeric and semielemental formulas with varying nutrient, caloric content, and triglyceride chain lengths have been demonstrated. In most formulas, RELiZORB efficiently hydrolyzed greater than 90% of fats within the formula into absorbable fatty acids and monoglycerides.

Nutritional status, nutrient intake and use of enzyme supplements in paediatric patients with Cystic Fibrosis; a European multicentre study with reference to current guidelines

BACKGROUND

The New European guidelines have established the most updated recommendations on nutrition and pancreatic enzyme replacement therapy (PERT) in CF. In the context of MyCyFAPP project - a European study in children with CF aimed at developing specific tools for improvement of self-management - the objective of the current study was to assess nutritional status, daily energy and macronutrient intake, and PERT dosing with reference to these new guidelines.

METHODS

Cross sectional study in paediatric patients with CF from 6 European centres. SD-scores for weight-for-age (WFA), height-for-age (HFA) and body mass index-for-age (BMI) were obtained. Through a specific 4-day food and enzyme-dose record, energy and macronutrients intake and PERT-use (LU/g lipids) were automatically calculated by the MyCyFAPP system. Comparisons were made using linear regression models.

RESULTS

The lowest quartiles for BMI and HFA were between 0 and -1SD in all the centres with no significant differences, and 33.5% of the patients had a SD-score <0 for all three parameters. The minimum energy intake recommendation was not reached by 40% of the children and mean nutrients intake values were 14%, 51% and 34% of the total energy for protein, carbohydrates and lipids respectively. When assessed per centre, reported PERT doses were in the recommended range in only 13.8% to 46.6% of the patients; from 5.6% up to 82.7% of children were above the recommended doses and 3.3% to 75% were below.

CONCLUSION

Among the 6 centres, a large variability and inconsistency with new guidelines on nutrition and PERT-use was found. Our findings document the lack of a general criterion to adjust PERT and suggest the potential benefit of educational and self-managerial tools to ensure adherence to therapies, both for clinical staff and families. They will be taken into account when developing these new tools during the next stages of MyCyFAPP Project.
