Health beliefs associated with poor disease self-management in smokers with asthma and/or COPD: a pilot study

Initiating and Maintaining Complete Decongestive Therapy Self-Management of Lymphedema Among Breast Cancer Survivors: Descriptive Qualitative Study

PURPOSE

This study aimed to identify determinants that promote the initiation and maintenance of complete decongestive therapy (CDT) as well as effective strategies for mitigating barriers to self-management of lymphedema among breast cancer survivors.

METHODS

A descriptive and qualitative design was used. In-depth interviews were conducted with 13 breast cancer survivors who were managing breast cancer-related lymphedema. Interviews were transcribed verbatim. An iterative descriptive data analysis method was employed to examine the data, compare codes, challenge interpretations, and inductively identify themes.

RESULTS

A realization that lymphedema requires daily self-management was the primary determinant leading breast cancer survivors to initiate CDT self-management. The determinants for maintaining daily CDT self-management included the perceived effectiveness of CDT, being willing to assume accountability, and perceived efficacy to undertake CDT. Developing strategies to integrate CDT regimens into daily life is key to maintaining CDT self-management of lymphedema. Three core concepts mediate initiation and maintenance of CDT self-management: understanding lymphedema as a chronic condition that can be managed with CDT self-management, being worried about lymphedema exacerbation, and having support from patient peers and family.

CONCLUSIONS

Interventions should be tailored to promote the initiation and maintenance of CDT self-management. While clinicians provided knowledge-based and clinical skills-based information, patient peers provided daily life examples, and real-life implementation strategies for CDT self-management. Ongoing patient-provider and patient-peer communication functioned as effective support for maintaining CDT self-management. Reliable and realistic methods of symptom self-assessment are important for maintaining CDT at home.

Treatment Adherence in Patients with Obstructive Pulmonary Diseases

COPD is the third most common cause of death globally. Adherence rates in patients with obstructive pulmonary diseases usually range between 10% and 40%. The aim of the study was to evaluate the level of treatment adherence to inhaled therapy in patients with obstructive pulmonary diseases. A total of 325 patients, of mean age 63.04 ± 11.29, with COPD or asthma, were included into the study between 2020 and 2021. The following questionnaires were used: Beliefs about Medicines Questionnaire, Test of Adherence to Inhalers and Adherence to Refills and Medications Scale. The respondents tended to be convinced of the necessity of their medication (3.87 points per question). The patients reported moderate levels of overall adherence (21.15 ± 6.23). A total of 74% of patients demonstrated sporadic non-compliance. We conclude that patients with obstructive pulmonary diseases are moderately adherent to their medication. Beliefs about medicines have a significant impact on adherence to medications. Being unemployed, being a non-smoker and belief in the necessity of medication are independent determinants of better medication adherence. The number of hospital admissions due to exacerbations of the disease over the last year and belief that medicines are harmful are independent determinants of poorer medication adherence.

The Impact of Tobacco Smoking on Adult Asthma Outcomes

Background: Tobacco smoking is associated with more severe asthma symptoms, an accelerated decline in lung function, and reduced responses to corticosteroids. Our objective was to compare asthma outcomes in terms of disease control, exacerbation rates, and lung function in a population of asthmatic patients according to their smoking status. Methods: We compared patients’ demographics, disease characteristics, and lung-function parameters in current-smokers (CS, n = 48), former-smokers (FS, n = 38), and never-smokers (NS, n = 90), and identified predictive factors for asthma control. Results: CS had a higher prevalence of family asthma/atopy, a lower rate of controlled asthma, impaired perception of dyspnea, an increased number of exacerbations, and poorer lung function compared to NS. The mean asthma control questionnaire’s (ACQ) score was higher in CS vs. NS and FS (1.9 vs. 1.2, p = 0.02). Compared to CS, FS had a lower rate of exacerbations, a better ACQ score (similar to NS), a higher prevalence of dyspnea, and greater lung-diffusion capacity. Non-smoking status, the absence of dyspnea and exacerbations, and a forced expiratory volume in one second ≥80% of predicted were associated with controlled asthma. Conclusions: CS with asthma exhibit worse clinical and functional respiratory outcomes compared to NS and FS, supporting the importance of smoking cessation in this population.

Antifungal Efficacy of Marine Macroalgae against Fungal Isolates from Bronchial Asthmatic Cases

Fungal sensitization is very common in bronchial asthmatic cases, and the connection with airway colonization by fungi remains uncertain. Antifungal therapy failure is a significant fraction of the cost and morbidity and mortality in the majority of the asthmatic cases. Hence, the present study aimed to investigate the antifungal activity of five marine macroalgae—Acanthaophora specifera, Cladophoropsis sp., Laurencia paniculata, Tydemania sp., and Ulva prolifera—which were tested on selected fungal pathogens isolated from 15 sputum of 45 bronchial asthmatic patients. The highest antifungal activity was observed in ethanol fractions of L. paniculata followed by U. prolifera, Cladophoropsis sp., A. specifera, and Tydemania sp. The minimum fungicidal concentration and minimum inhibitory concentration values of the ethanolic fractions of algal species were found to be 125–1000 µg/mL and 125–500 µg/mL, respectively. The algal extracts contained terpene alcohol, diterpene, steroids, sesquiterpene, and sesquiterpene alcohol, as determined by GC–MS/MS analyses. The present study shows that the marine macroalgae containing bioactive compounds had excellent inhibitory activity against a variety of fungal pathogens, which may be useful for combating fungal infections and recovering from chronic asthmatic states.
