    Music Listening as a Stress-Reduction Tool for Overweight Individuals: Evidence from a Randomized Trial

    by Isabela Peres Carvalho, Juliana Beaudette Drummond, Antônio Ribeiro-Oliveira Júnior, Frederico Gonçalves Pedrosa

    This randomized controlled trial evaluated the effects of a single music listening session on stress reduction in overweight individuals (BMI > 24.9 kg/m2). Participants were allocated to an experimental group (music listening, n = 28) or a control group (podcast listening, n = 26). Stress was assessed through salivary cortisol, subjective scales (VAS), and qualitative topic modeling. Data were analyzed using Linear Mixed-Effects Models (LMM) and post-hoc Wilcoxon tests with Bonferroni correction. The experimental group exhibited a highly significant reduction in cortisol (padj < 0.001) with a large effect size (r = 0.59), while the control group’s reduction did not reach statistical significance after adjustment (padj = 0.07, r = 0.37). Responder analysis showed a 92.9% success rate for music versus 80.8% for podcasts (Odds Ratio = 3.03). Subjective and qualitative data revealed a broader spectrum of relaxation and sensory immersion in the experimental group. Music listening is a superior, predictable, and low-cost tool for neuroendocrine stabilization in overweight individuals, outperforming purely narrative stimuli.

    Treatment Patterns, Adherence, Persistence, and Health Care Resource Utilization in Acromegaly: A Real-World Analysis

    by Maria Fleseriu, Ariel Barkan, Thierry Brue, Edouard Duquesne, Aude Houchard, Maria del Pilar Schneider, Antonio Ribeiro-Oliveira, Shlomo Melmed

    Context: Treatment of acromegaly is multimodal for many patients, and medical treatments include somatostatin receptor ligands (SRLs), dopamine agonists (DAs), and growth hormone receptor antagonists (GHRAs). However, recent real-world evidence on treatment patterns for patients with acromegaly is limited. Objective: This study evaluated medication usage, treatment changes, adherence, persistence, comorbidities, and health care resource utilization using deidentified data from MarketScan, a US claims database. Methods: Eligible patients (n = 882) were those receiving monotherapy or combination therapy for ≥90 days without treatment gaps. Results: Mean age at diagnosis was 48.6 years; 50.1% of patients were female. Over half (59.4%) had 1 line of treatment (LOT); 23.1% had 2 LOTs; 17.5% had at least 3 LOTs. Most patients (94.6%) initiated treatment with monotherapies. The most common first-line monotherapy treatments were cabergoline (DA, 36.8%), octreotide long-acting release (first-generation SRL, 29.5%), and lanreotide depot (first-generation SRL, 22.5%). Adherence for first-line treatments (proportion of days covered) was higher for first-generation SRLs (lanreotide depot: 0.8) compared with DAs (0.7). Treatment persistence (time between the first treatment record and a change in LOT/censoring) in LOT 1 was higher for GHRAs (24.8 months) and first-generation SRLs (20.0 months) compared with DAs (14.4 months). Female patients and those diagnosed at a younger age were more likely to have shorter treatment persistence. The most prevalent comorbidities were hyperlipidemia, essential hypertension, and sleep apnea. Conclusion: Patients with more comorbidities had more health care visits during the first year after diagnosis, suggesting increased disease burden. Real-world evidence on treatment patterns provides insights into recommendations for individualized therapy.

    An international simulated-use study to assess nurses’ preferences between two lanreotide syringes for patients with neuroendocrine tumours or acromegaly (PRESTO 3)

    by D. Ferone, W. Martin, J. Williams, A. Houchard, C. Pommie, A. Ribeiro-Oliveira, A. B. Grossman

    Purpose: PRESTO 3 evaluated nurses’ preference for the Somatuline® Autogel® syringe versus the Lanreotide Pharmathen syringe after injection-pad testing. Methods: This international simulated-use study included oncology/endocrinology nurses with ≥ 1 years’ experience in managing neuroendocrine tumours (NETs) and/or acromegaly. Each nurse tested both syringes twice in a randomised order before completing an electronic survey. The primary objective was to assess overall preference (%, 95% confidence interval [CI]) for the Somatuline Autogel syringe versus the Lanreotide Pharmathen syringe. Secondary objectives included rating syringe performance and ranking the importance of syringe attributes. Results: Ninety-four nurses were enrolled: mean age, 41.0 (SD, 11.5) years. The percentage of nurses stating a preference (“strong” or “slight”) for the Somatuline Autogel syringe (86.2% [95% CI 77.5–92.4%]) was significantly higher than 50% (p < 0.0001). Performance rating was significantly higher for the Somatuline Autogel syringe versus Lanreotide Pharmathen syringe for 10 of the 11 attributes tested (p < 0.05). The syringe attributes considered most important when injecting patients in routine clinical practice were “easy to use from preparation to injection” (30.9%) and “comfortable to handle during use from preparation to injection” (16.0%). The attribute most commonly rated as least important was “fast administration from preparation to injection” (26.6%). Conclusion: Nurses strongly preferred the user experience of the Somatuline Autogel syringe over the Lanreotide Pharmathen syringe. “Ease of use” and “comfortable to handle” were the most important syringe attributes, and performance rating was significantly higher with Somatuline Autogel versus Lanreotide Pharmathen syringe for all but one attribute.

  • PRESTO 2: An International Survey to Evaluate Patients’ Injection Experiences with the Latest Devices/Formulations of Long-Acting Somatostatin Analog Therapies for Neuroendocrine Tumors or Acromegaly

    by Dermot O’tOole, Pamela L. Kunz, Susan M. Webb, Grace Goldstein, Sheila Khawaja, Mark McDonnell, Sandra Boiziau, Delphine Gueguen, Aude Houchard, Antonio Ribeiro-Oliveira, et al.

    Introduction Real-world data evaluating patients’ injection experiences using the latest devices/formulations of the long-acting (LA) somatostatin analogs (SSAs) lanreotide Autogel/Depot (LAN; Somatuline®) and octreotide LA release (OCT; Sandostatin®) are limited. Methods PRESTO 2 was a 2020/2021 e-survey comparing injection experience of adults with neuroendocrine tumors (NETs) or acromegaly treated with LAN prefilled syringe versus OCT syringe for > 3 months in Canada, Ireland, the UK and the USA (planned sample size, 304). Primary endpoint: the proportion of patients with injection-site pain lasting > 2 days after their most recent injection, analyzed using a multivariate logistic regression model. Secondary endpoints included interference with daily life due to injection-site pain and technical injection problems in patients with current SSA use for ≥ 6 months. Results There were 304 respondents (acromegaly, n = 85; NETs, n = 219; LAN, n = 168; OCT, n = 136; 69.2% female; mean age, 59.6 years). Fewer patients had injection-site pain lasting > 2 days after the most recent injection with LAN (6.0%) than OCT (22.8%); the odds of pain lasting > 2 days were significantly lower for LAN than OCT, adjusted for disease subgroup and occurrence of injection-site reactions (odds ratio [95% confidence interval]: 0.13 [0.06–0.30]; p < 0.0001). Injection-site pain interfered with daily life “a little bit” or “quite a bit” in 37.2% and 3.8% (LAN) versus 52.5% and 7.5% (OCT) of patients, respectively. Among patients with ≥ 6 months’ experience with current SSA (92.4% of patients), technical injection problems never occurred in 76.8% (LAN) and 42.9% (OCT) of patients. Conclusions Compared with OCT, significantly fewer patients using LAN had injection-site pain lasting > 2 days after their most recent injection. Also, fewer LAN-treated patients experienced technical problems during injection. These findings demonstrate the importance of injection modality for overall LA SSA injection experience for patients with acromegaly or NETs. Graphical abstract

    A systematic literature review to evaluate extended dosing intervals in the pharmacological management of acromegaly

    by M. Fleseriu, Z. Zhang, K. Hanman, K. Haria, A. Houchard, S. Khawaja, A. Ribeiro-Oliveira, M. Gadelha

    Purpose: This systematic literature review investigated whether extended dosing intervals (EDIs) of pharmacological acromegaly treatments reduce patient burden and costs compared with standard dosing, while maintaining effectiveness. Methods: MEDLINE/Embase/the Cochrane Library (2001–June 2021) and key congresses (2018–2021) were searched and identified systematic literature review bibliographies reviewed. Included publications reported on efficacy/effectiveness, safety and tolerability, health-related quality of life (HRQoL), and patient-reported and economic outcomes in longitudinal/cross-sectional studies in adults with acromegaly. Interventions included EDIs of pegvisomant, cabergoline, and somatostatin receptor ligands (SRLs): lanreotide autogel/depot (LAN), octreotide long-acting release (OCT), pasireotide long-acting release (PAS), and oral octreotide; no comparator was required. Results: In total, 35 publications reported on 27 studies: 3 pegvisomant monotherapy, 11 pegvisomant combination therapy with SRLs, 9 LAN, and 4 OCT; no studies reported on cabergoline, PAS, or oral octreotide at EDIs. Maintenance of normal insulin-like growth factor I (IGF-I) was observed in ≥ 70% of patients with LAN (1 study), OCT (1 study), and pegvisomant monotherapy (1 study). Achievement of normal IGF-I was observed in ≥ 70% of patients with LAN (3 studies) and pegvisomant in combination with SRLs (4 studies). Safety profiles were similar across EDI and standard regimens. Patients preferred and were satisfied with EDIs. HRQoL was maintained and cost savings were provided with EDIs versus standard regimens. Conclusions: Clinical efficacy/effectiveness, safety, and HRQoL outcomes in adults with acromegaly were similar and costs lower with EDIs versus standard regimens. Physicians may consider acromegaly treatment at EDIs, especially for patients with good disease control.


  • Evaluating home injection compared with healthcare-setting injection of somatostatin analogs: a systematic literature review

    by Cesar L. Boguszewski, Márta Korbonits, Audrey Artignan, Almudena Martín García, Aude Houchard, Antonio Ribeiro-Oliveira, Wouter W. de Herder

    Purpose A systematic literature review was conducted to assess the use of home injections (self/partner/healthcare provider [HCP]-administered) of somatostatin analogs (SSAs) as an alternative to healthcare-setting injections in patients with acromegaly and neuroendocrine tumors (NETs). Methods MEDLINE/Embase/the Cochrane Library (2001–September 2021), key congresses (2019–2021), and bibliographies of relevant systematic reviews were searched. Eligible studies reported on efficacy/effectiveness, safety, adherence, patient-reported outcomes (PROs), and economic outcomes in populations receiving home injections of SSAs. Results Overall, 12 studies were included, all reporting on SSAs (lanreotide Autogel/Depot or octreotide long-acting release) in acromegaly or NETs. Across four studies, home injection was associated with similar disease control in patients with acromegaly/NETs compared with healthcare-setting administration. High rates of treatment adherence were shown in two studies of patients with acromegaly receiving lanreotide injections at home. Two studies reported non-serious adverse events; incidence of adverse reactions was similar in both the home and healthcare administration settings. Preference for injection setting varied between studies and indications; nonetheless, higher satisfaction/convenience (>75% patients) was reported for home injections. Self- or partner-injection was associated with economic savings compared with administration in the healthcare setting across five studies. Conclusion Efficacy/effectiveness, adherence, and safety outcomes of SSAs in the home injection setting were similar to those in the healthcare setting, with high reported satisfaction and convenience. Self/partner injection also resulted in cost savings. These findings provide a basis to understand outcomes related to home injection and encourage healthcare providers to discuss optimal treatment choices with their patients.

    Assessment of the performance of the Brazilian Portuguese Nottingham Health Profile in adult growth hormone deficiency and pulmonary hypertension

    by Alice Heaney, Rafael W. R. de Oliveira, Mariana Bizzi, Ricardo Amorim Correa, Monica Corso Pereira, Suelem Simao Mol, Beatriz Santana Soares, Stephen P. McKenna, Antonio Ribeiro-Oliveira Jr, Study Investigators

    Background: The Nottingham Health Profile (NHP) is a generic measure of perceived distress that has been used widely as an outcome measure in clinical practice and trials. The availability of two Brazilian datasets provided the opportunity to assess the psychometric performance of the NHP in different populations - adult growth hormone deficiency (GHD) and pulmonary hypertension (PH). The purpose of the study was to see how valuable the NHP could be in assessing outcomes in diseases where no disease-specific measures are available. Methods: Secondary analyses were performed with NHP data. Patients diagnosed with adult GHD or PH were administered the NHP during clinic visits on two occasions, two weeks apart. A disease-specific measure of quality of life (QoL) was also administered to the relevant sample of patients on each occasion. Results: The psychometric properties of the NHP were good for both disease groups. As expected, both samples reported high scores on energy level, the PH sample scored high on physical functioning and the GHD sample on emotional reactions. For both samples, most of the NHP sections were able to distinguish between groups of respondents with different ratings of perceived general health. While most sections of the NHP were relatively highly correlated with the QoL measures, pain and sleep did not seem to be important predictors of QoL in either of the samples. Conclusions: The use of the NHP in adult GHD and PH populations in Brazil is not recommended as there are high-quality disease-specific measures available for each disease. However, where no disease-specific measures are available, the NHP can provide good descriptive information of the impact of disease on different patient populations.
