Burden of chronic cough in the UK: results from the 2018 National Health and Wellness Survey.

Background: Chronic cough, defined as daily cough for at least 8 weeks, negatively affects quality of life and work productivity and increases healthcare resource utilisation. We aimed to determine the prevalence and burden of chronic cough in the UK. Methods: Study participants were general population respondents to the 2018 UK National Health and Wellness Survey (NHWS). Respondents completed survey questions relating to health, quality of life, work productivity and activity impairment, and use of healthcare resources. Prevalence estimates were projected to the UK population using post-stratification sampling weights to adjust for sampling bias. The population with chronic cough was matched 1:3 with a group without chronic cough, using propensity score matchingon age, sex and the modified Charlson Comorbidity Index. Results: Of 15 000 NHWS respondents, 715 reported chronic cough in the previous 12 months and 918 during their lifetime. Weighted to the UK adult population, the 12-month prevalence of chronic cough was 4.9% and lifetime prevalence was 6.2%. Prevalence of chronic cough was higher among older respondents and those with smoking histories. Chronic cough respondents experienced higher rates of severe anxiety and depression in the past 2 weeks than matched controls. Poor sleep quality and loss of work productivity were also observed. More chronic cough respondents visited a healthcare provider in the past 6 months than respondents without chronic cough with a mean of 5.8 and 3.7 visits per respondent, respectively. Conclusion: Adults with chronic cough report lower quality of life, reduced work productivity and greater healthcare resource utilisation than matched controls without chronic cough.

[Identification of epithelial-mesenchymal transition markers (EMT) by immunohistochemistry in pediatric osteosarcoma and association with clinical outcomes]. / Identificación de marcadores de transición epitelio-mesénquima (TEM) por inmunohistoquímica en osteosarcoma pediátrico y asociación con desenlaces clínicos.

The epithelial-mesenchymal transition (EMT) is the ability of epithelial and mesenchymal cells to exchange phenotypes transiently. Its identification in carcinomatous cells has been associated with aggressive clinical phenotypes. In sarcomas, this ability is under study. OBJECTIVE: to evaluate the expression of two transcription factors involved in EMT by immunohistochemistry in pediatric osteosarcoma and its association with clinical outcomes. PATIENTS AND METHOD: A retrospective cohort study in children under 18 years of age with osteosarcoma diagnosis. Immunohistochemistry was performed for Snail and Twist-1 expressions from samples collected at the time of diagnosis. Correlations between immunohistochemistry and the clinical outcomes and overall survival were performed. RESULTS: 53 patients were included. There were 26 positive cytoplasmic cases (49.1%) in Snail expression and were correlated with the presence of multiple metastases (p = 0.02) and distant bone metastases (p = 0.01). On the other hand, 45 cases (84.9%) were positive in Twist-1 expression in the nuclear location, showing no association with the analyzed clinical variables. CONCLUSIONS: Snail and Twist-1 were frequently expressed in pediatric cases of osteosarcoma. Cytoplasmic Snail was correlated with the presence of multiple metastatic disease and distant bone metastases. The positivity of both markers suggests the activation of these proteins as regulators of EMT events in this tumor, suggesting a role in the phenomena related to the clinical presentation of the disease.

Clinical Characteristics and Outcomes of a Cohort of Pediatric Oncohematologic Patients With COVID-19 Infection in the City of Bogotá, Colombia.

BACKGROUND: In children, the complications of severe acute respiratory syndrome coronavirus 2 infection occur less frequently than in adults but the characteristics of this disease in oncology patients are not well characterized. METHODS: This was a retrospective study in patients younger than 18 years of age with coronavirus disease 2019 (COVID-19) and cancer diagnoses between April and September 2020. Demographic variables, laboratory, and radiologic findings and complications of each case were identified. A descriptive analysis was performed. RESULTS: A total of 33 patients were identified; the median age was 10 years. Fifteen patients (42%) were in chemotherapy at the time of the infection diagnosis, in two patients the chemotherapy protocol was permanently suspended. The most common symptom was fever in 20 patients (60%). Seven patients (21.2%) showed mild pneumonia, four patients (12.1%) severe pneumonia, and three cases (9.0%) were classified as critical. In the evaluated cohort, five patients (15.1%) died, and in two of those, death was caused by COVID-19 infection. CONCLUSIONS: Children with an oncologic disease, the search for COVID cases should be oriented to patients with fever, including febrile neutropenia, the presence of respiratory symptoms, and the search for epidemiologic contact. A higher frequency of complications and mortality attributed to COVID-19, two in pediatric oncohematologic patients was found. Institutional strategies to detect the infection early and lower institutional infection are indicated.

Impact of a Copayment Reduction Intervention on Medication Persistence and Cardiovascular Events in Hospitals With and Without Prior Medication Financial Assistance Programs.

Background Hospitals commonly provide a short-term supply of free P2Y12 inhibitors at discharge after myocardial infarction, but it is unclear if these programs improve medication persistence and outcomes. The ARTEMIS (Affordability and Real-World Antiplatelet Treatment Effectiveness After Myocardial Infarction Study) trial randomized hospitals to usual care versus waived P2Y12 inhibitor copayment costs for 1-year post-myocardial infarction. Whether the impact of this intervention differed between hospitals with and without pre-existing medication assistance programs is unknown. Methods and Results In this post hoc analysis of the ARTEMIS trial, we examined the associations of pre-study free medication programs and the randomized copayment voucher intervention with P2Y12 inhibitor persistence (measured by pharmacy fills and patient report) and major adverse cardiovascular events using logistic regression models including a propensity score. Among 262 hospitals, 129 (49%) offered pre-study free medication assistance. One-year P2Y12 inhibitor persistence and major adverse cardiovascular events risks were similar between patients treated at hospitals with and without free medication programs (adjusted odds ratio 0.93, 95% CI, 0.82-1.05 and hazard ratio 0.92, 95% CI, 0.80-1.07, respectively). The randomized copayment voucher intervention improved persistence, assessed by pharmacy fills, in both hospitals with (53.6% versus 44.0%, adjusted odds ratio 1.45, 95% CI, 1.20-1.75) and without (59.0% versus 48.3%, adjusted odds ratio 1.46, 95% CI, 1.25-1.70) free medication programs (Pinteraction=0.71). Differences in patient-reported persistence were not significant after adjustment. Conclusions While hospitals commonly report the ability to provide free short-term P2Y12 inhibitors, we did not find association of this with medication persistence or major adverse cardiovascular events among patients with insurance coverage for prescription medication enrolled in the ARTEMIS trial. An intervention that provided copayment assistance vouchers for 1 year was successful in improving medication persistence in hospitals with and without pre-existing short-term medication programs.

Association of a P2Y12 Inhibitor Copayment Reduction Intervention With Persistence and Adherence With Other Secondary Prevention Medications: A Post Hoc Analysis of the ARTEMIS Cluster-Randomized Clinical Trial.

Importance: The Affordability and Real-World Antiplatelet Treatment Effectiveness After Myocardial Infarction Study (ARTEMIS) cluster-randomized trial found that copayment reduction for P2Y12 inhibitors improved 1-year patient persistence in taking that medication. Objective: To assess whether providing copayment reduction for P2Y12 inhibitors increases patient persistence in taking other secondary prevention cardiovascular medications. Design, Setting, and Participants: This post hoc analysis of the ARTEMIS trial includes data from 287 hospitals that enrolled patients between June 2015 and September 2016. Patients hospitalized with acute myocardial infarction were included. Data analysis occurred from May 2018 through August 2019. Interventions: Hospitals randomized to the intervention provided patients vouchers that waived copayments for P2Y12 inhibitors fills for 1 year. Hospitals randomized to usual care did not provide study vouchers. Main Outcomes and Measures: Persistence in taking ß-blocker, statin, and angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker medications at 1 year, defined as the absence of a gap in medication supply of 30 or more days by pharmacy fill data in the intervention-arm (intent-to-treat) population. Results: A total of 131 hospitals (with 5109 patients) were randomized to the intervention, and 156 hospitals (with 3264 patients) randomized to the control group. Patients discharged from intervention hospitals had higher persistence in taking statins (2247 [46.1%] vs 1300 [41.9%]; adjusted odds ratio, 1.11 [95% CI, 1.00-1.24]), and ß-blockers (2235 [47.6%] vs 1277 [42.5%]; odds ratio, 1.23 [95% CI, 1.10-1.38]), although the association was smaller than that seen for P2Y12 inhibitors (odds ratio, 1.47 [95% CI, 1.29-1.66]). Persistence in taking angiotensin-converting enzyme inhibitors or angiotensin II-receptor blockers were also numerically higher among patients in the intervention arm than in the usual-care arm, but this was not significant after risk adjustment (1520 [43.9%] vs 847 [40.5%]; adjusted odds ratio, 1.10 [95% CI, 0.97-1.24]). Patients in the intervention arm reported greater financial burden associated with medication cost than the patients in the usual-care arm at baseline, but these differences were no longer significant at 1 year. Conclusions and Relevance: Reducing patient copayments for 1 medication class increased persistence not only to that therapy class but may also have modestly increased persistence to other post-myocardial infarction secondary prevention medications. These findings have important implications for the clinical utility and cost-effectiveness of medication cost-assistance programs. Trial Registration: ClinicalTrials.gov identifier: NCT02406677.

Pharmacogenomic and pharmacogenetic-guided therapy as a tool in precision medicine: current state and factors impacting acceptance by stakeholders.

Pharmacogenetic/pharmacogenomic (PGx) testing is currently available for a wide range of health problems including cardiovascular disease, cancer, diabetes, autoimmune disorders, mental health disorders and infectious diseases. PGx contributes important information to the field of precision medicine by clarifying appropriate treatments for specific disease subtypes. Tangible benefits to patients including improved outcomes and reduced total health care costs have been observed. However, PGx-guided therapy faces many barriers to full integration into clinical practice and acceptance by stakeholders, whether practitioner, patient or payer. Each stakeholder has a unique perspective on the role of PGx testing, although all are similarly challenged with demonstrating or appraising its cost-to-benefit value. Coverage by insurers is a critical step in achieving widespread adoption of PGx testing. The acceleration of adoption of precision medicine in general and for PGx testing in particular will be determined by how quickly robust evidence can be accumulated that shows a return on investment for payers in terms of real dollars, for clinicians in terms of patient clinical responses, and for patients in terms of economic, health and quality of life outcomes. Trends in PGx testing utilization and uptake by payers in real-world practice are discussed; the role of pharmacoeconomics in assessing cost-effectiveness is highlighted using a case study in psychiatric care, and several issues that will affect adoption of PGx testing in the United States (US) over the next few years are reviewed.

Treatment patterns: targeted therapies indicated for first-line management of metastatic renal cell carcinoma in a real-world setting.

BACKGROUND: Limited information on real-world treatment patterns of targeted agents for metastatic renal cell carcinoma (mRCC) is available to inform their use in clinical practice. PATIENTS AND METHODS: This retrospective observational study used US claims data (from January 2007 to November 2010) to identify treatment patterns, including treatment duration and dosing, for molecular-targeted agents (sunitinib, sorafenib, pazopanib, bevacizumab, and temsirolimus) indicated in first-line management of advanced and/or mRCC. The study included adult patients with mRCC who were observable for ≥3 months after initiation of their first-line therapy with a targeted agent. Descriptive analyses were conducted for observed treatment patterns. RESULTS: Of the 273 patients on first-line therapy identified and included in the sample, 235 patients were treated with sunitinib, 16 patients with sorafenib, and 15 patients with temsirolimus. Pazopanib and bevacizumab were excluded from the analysis due to the small sample size, n < 10. The median observed treatment durations were sunitinib 98 days, sorafenib 121 days, and temsirolimus 78 days. Approximately 76% (178/235) of patients who received sunitinib initiated therapy at the indicated dose of 50 mg; 65% of these patients were not observed filling a fourth prescription, whereas 23% maintained their starting dose and 12% experienced dose reduction at their 4+ fill. The mean starting dose for patients who initiated on sorafenib (n = 16) was 725 mg and for temsirolimus (n = 15) was 25 mg: their study samples were insufficient for further, meaningful dosing analyses. CONCLUSIONS: Results of this study suggest that opportunities exist to improve treatment duration in clinical practice and to better understand influences on treatment and dose changes.

Cost of palliative radiation to the bone for patients with bone metastases secondary to breast or prostate cancer.

BACKGROUND: To estimate the costs (paid amounts) of palliative radiation episodes of care (REOCs) to the bone for patients with bone metastases secondary to breast or prostate cancer. METHODS: Claims-linked medical records from patients at 98 cancer treatment centers in 16 US states were analyzed. Inclusion criteria included a primary neoplasm of breast or prostate cancer with a secondary neoplasm of bone metastases; ≥2 visits to ≥1 radiation center during the study period (1 July 2008 through 31 December 2009) on or after the metastatic cancer diagnosis date; radiation therapy to ≥1 bone site; and ≥1 complete REOC as evidenced by a >30-day gap pre- and post-radiation therapy. RESULTS: The total number of REOCs was 220 for 207 breast cancer patients and 233 for 213 prostate cancer patients. In the main analysis (which excluded records with unpopulated costs) the median number of fractions per a REOC for treatment of metastases was 10. Mean total radiation costs (i.e., radiation direct cost + cost of radiation-related procedures and visits) per REOC were $7457 for patients with breast cancer and $7553 for patients with prostate cancer. Results were consistent in sensitivity analyses excluding patients with unpopulated costs. CONCLUSIONS: In the US, current use of radiation therapy for bone metastases is relatively costly and the use of multi-fraction schedules remains prevalent.
