Exhaled volatile organic compounds associated with risk factors for obstructive pulmonary diseases: a systematic review.

Background: Asthma and COPD are among the most common respiratory diseases. To improve the early detection of exacerbations and the clinical course of asthma and COPD new biomarkers are needed. The development of noninvasive metabolomics of exhaled air into a point-of-care tool is an appealing option. However, risk factors for obstructive pulmonary diseases can potentially introduce confounding markers due to altered volatile organic compound (VOC) patterns being linked to these risk factors instead of the disease. We conducted a systematic review and presented a comprehensive list of VOCs associated with these risk factors. Methods: A PRISMA-oriented systematic search was conducted across PubMed, Embase and Cochrane Libraries between 2000 and 2022. Full-length studies evaluating VOCs in exhaled breath were included. A narrative synthesis of the data was conducted, and the Newcastle-Ottawa Scale was used to assess the quality of included studies. Results: The search yielded 2209 records and, based on the inclusion/exclusion criteria, 24 articles were included in the qualitative synthesis. In total, 232 individual VOCs associated with risk factors for obstructive pulmonary diseases were found; 58 compounds were reported more than once and 12 were reported as potential markers of asthma and/or COPD in other studies. Critical appraisal found that the identified studies were methodologically heterogeneous and had a variable risk of bias. Conclusion: We identified a series of exhaled VOCs associated with risk factors for asthma and/or COPD. Identification of these VOCs is necessary for the further development of exhaled metabolites-based point-of-care tests in these obstructive pulmonary diseases.

Medication use in uncontrolled pediatric asthma: Results from the SysPharmPediA study.

BACKGROUND: Uncontrolled pediatric asthma has a large impact on patients and their caregivers. More insight into determinants of uncontrolled asthma is needed. We aim to compare treatment regimens, inhaler techniques, medication adherence and other characteristics of children with controlled and uncontrolled asthma in the: Systems Pharmacology approach to uncontrolled Paediatric Asthma (SysPharmPediA) study. MATERIAL AND METHODS: 145 children with moderate to severe doctor-diagnosed asthma (91 uncontrolled and 54 controlled) aged 6-17 years were enrolled in this multicountry, (Germany, Slovenia, Spain, and the Netherlands) observational, case-control study. The definition of uncontrolled asthma was based on asthma symptoms and/or exacerbations in the past year. Patient-reported adherence and clinician-reported medication use were assessed, as well as lung function and inhalation technique. A logistic regression model was fitted to assess determinants of uncontrolled pediatric asthma. RESULTS: Children in higher asthma treatment steps had a higher risk of uncontrolled asthma (OR (95%CI): 3.30 (1.56-7.19)). The risk of uncontrolled asthma was associated with a larger change in FEV1% predicted post and pre-salbutamol (OR (95%CI): 1.08 (1.02-1.15)). Adherence and inhaler techniques were not associated with risk of uncontrolled asthma in this population. CONCLUSION: This study showed that children with uncontrolled moderate-to-severe asthma were treated in higher treatment steps compared to their controlled peers, but still showed a higher reversibility response to salbutamol. Self-reported adherence and inhaler technique scores did not differ between controlled and uncontrolled asthmatic children. Other determinants, such as environmental factors and differences in biological profiles, may influence the risk of uncontrolled asthma in this moderate to severe asthmatic population.

Evaluation of the Factors Associated with Prescribed and Non-Prescribed Medicine: A Population-Based Study.

OBJECTIVES: Several factors influence medication patterns. The purpose of this study was to look into the role of social determinants in the use of prescribed and non-prescribed medications in a population-based setting of people over 18 in a southern metropolis of Iran (Shiraz) for 2 years. STUDY DESIGN: Prospective population-based cross-sectional. METHODS: This descriptive and cross-sectional survey was done in 2018-2020. A total of 1016 participants were randomly selected based on their postal codes and recruited to the study. The demographic characteristics (age, sex, and education), social profiles (insurance, supplementary insurance, health status, and daily exercise plan), and outpatient visits (family/general physician or specialist/ subspecialist) were recorded by gathering sheets. Descriptive analyses and multinomial logistic analyses were carried out using SPSS software. RESULTS: The medication use pattern was classified into three categories: non-prescribed type I, non-prescribed type II, and prescribed. The mean age of participants was 45.54 ± 15.82 years. The results indicated that most of them took their medication without a prescription (non-prescribed type II). However, people who had insurance and referred to a family physician commonly used the prescribed medications. This study also found that patients who visited a family doctor or a general practitioner used fewer prescribed drugs than those who visited a specialist. CONCLUSION: This study describes social determinants as additional effective factors in health services that influence the use of prescribed and non-prescribed medications in Shiraz. These evidence- based findings can help policymakers to plan the best programs.

Recent advances in the treatment of childhood asthma: a clinical pharmacology perspective.

INTRODUCTION: Childhood asthma is a complex heterogenous inflammatory disease that can pose a large burden on patients and their caregivers. There is a strong need to adapt asthma treatment to the individual patient taking into account underlying inflammatory profiles, moving from a 'one size fits all' approach toward a much-needed personalized approach. AREAS COVERED: This review article aims to provide an overview of recent advances in the management and treatment of pediatric asthma, including novel insights on the molecular heterogeneity of childhood asthma, the emergence of biologicals to treat severe asthma, and innovative e-health and home monitoring techniques to make asthma management more convenient and accessible. EXPERT OPINION: Molecular technologies have provided new treatment leads. E-health and home monitoring technologies have helped to gain more insights into disease dynamics and improve adherence to treatment while bringing health care to the patient. However, uncontrolled childhood asthma is still a major unmet clinical need and precision-medicine approaches are still scarce in clinical practice. Advanced omics methods may help researchers or clinicians to more accurately phenotype and treat subtypes of childhood asthma and gain more insight into the complexity of the disease.

Evaluation of factors that influenced the length of hospital stay using data mining techniques.

BACKGROUND: length of stay (LOS) is the time between hospital admission and discharge. LOS has an impact on hospital management and hospital care functions. METHODS: A descriptive, retrospective study was designed on about 27,500 inpatients between March 2019 and 2020. Required data were collected from six wards (CCU, ICU, NICU, General, Maternity, and Women) in a teaching hospital. Clinical data such as demographic characteristics (age, sex), type of ward, and duration of hospital stay were analyzed by the R-studio program. Violin plots, bar charts, mosaic plots, and tree-based models were used to demonstrate the results. RESULTS: The mean age of the population was 40.8 ± 19.2 years. The LOS of the study population was 2.43 ± 4.13 days. About 60% of patients were discharged after staying one day in the hospital. After staying one day in the hospital, 67% of women were discharged. However, 23% of men were discharged within this time frame. The majority of LOS in the CCU, ICU, and NICU ranged from 5 to 9 days.; In contrast, LOS was one day in General, Maternity, and Woman wards. Due to the tree plot, there was a different LOS pattern between Maternity-Women and the CCU-General-ICU-NICU wards group. CONCLUSION: We observed that patients with more severe diseases hospitalized in critical care wards had a longer LOS than those not admitted to critical care wards. The older patient had longer hospital LOS than the younger. By excluding Maternity and Woman wards, LOS in the hospital was comparable between males and females and demonstrated a similar pattern.

Assessing the Performance of Community Pharmacies in Iran by Measuring Responsiveness to Non-Medical Needs: An Application of WHO Responsiveness Framework.

OBJECTIVE: Despite growing debates about the health systems' nonmedical performance, there has not been any empirical research on nonmedical performance and patients' rights consideration as a driver of human rights in the pharmaceutical sector. This study's main objective was to assess the nonmedical performance of community pharmacies of Shiraz, Iran. METHODS: A cross-sectional study was conducted using two self-administrated Likert-based questionnaires based on the World Health Organization (WHO) responsiveness framework and the legal charter communicated by the Ministry of Health and Medical Education of Iran. The population was patients older than 18 years who took a prescription from community pharmacies located in Shiraz and willing to answer the questions voluntarily, from 2018 to 2019. Considering the weights of subdimensions of responsiveness provided by the WHO framework, the total score of responsiveness was calculated ranging from 0 to 100. FINDINGS: The response rate was 80.5%. The mean (standard deviation) overall score of responsiveness was 57.18 (21.61), with a median of 56.71. The mean score of client orientation was lower in respondents with a high education level than those with a diploma and under diploma (P = 0.028). CONCLUSION: Nonmedical pharmacy performance was considered either medium or high in more than half of the cases based on the participants' views. Regarding client, orientation was seen less often in patients with high education level compared to those with a lower education level.

The Pattern of Medication Usage in the Southern Region of Iran: A population-based Pharmacoepidemiological Study.

OBJECTIVE: The purpose of this study was to document the demographic data, to assess the proportion of consumed medicines and the amounts and types of drugs available to households, and to to estimate the probable prevalence of certain diseases in the southern region of Iran. METHODS: In this cross-sectional population-based study carried out in Shiraz (the central city in the Southern part of Iran), we documented and evaluated the drug usage details in a random sample of 1000 households during 2018-2020. We analyzed the usage of drug categories based on the anatomical therapeutic chemical classification, which the World Health Organization recommends. FINDINGS: In the studied population, the average age (± standard deviation) was 45.54 ± 15.82, ranged 18-91 years. More than 90% had medical insurance coverage. About 81.8% of the participants had individual family medicine practitioners, and most of them (93.8%) received medications with a physician's prescription. The most frequently used medications were cough and cold preparations (12.9%), nervous system drugs (12.6%), and cardiovascular system drugs (11.6%). CONCLUSION: Despite the easy access to medications for most participants, few individuals (about 6%) received their medications without a prescription. The most frequently prescribed medicines were the common cold, acetaminophen, and metformin. Common cold, gastrointestinal (GI) disorder, and diabetes were the most commonly used medication classes. Furthermore, we have found a probably higher than average prevalence of cardiovascular, GI, and endocrine disorders. This information could be used by the local policymakers as a basis for the estimation and allotment of health-care resources.
