Socioeconomic status (SES) data were collected from questionnaires and this form was sent to the patients via e-mail. Parameters related to social status and poor disease control were analyzed.ResultsIlliteracy (OR:2.687 [95% CI: 1.235-5.848]; p = 0.013) and lower household income (OR:1,76 [95% CI: 1.002-3.09]; p = 0.049) were found as independent risk factors for hospitalization in the multivariate logistic regression analysis. Therewithal, being aged between 40 and 60 (OR: 1.435 [95% CI: 1.074-1.917]; p = 0.015), illiteracy (OR: 2.188 [95% CI: 1.262-3.795]; p = 0.005) and being employed (OR: 1.466 [95% CI: 1.085-1.847]; p = 0.011) were considered as independent risk factors for systemic corticosteroid use at least 3 days within last 1 year.ConclusionAs a result of our national database, education level, household income and working status briefly socioeconomic status have impacts on asthma control. Identification of social markers in asthma and better recognition of risk factors based on the population gives us clues to provide better asthma control in the future.Item Picturing asthma in Turkey: results from the Turkish adult asthma registryCelik, GE; Aydin, O; Gokmen, D; Buhari, GK; Sozener, ZC; Gemicioglu, B; Bulut, I; Beyaz, S; Orcen, C; Ozdemir, SK; Keren, M; Damadoglu, E; Yakut, T; Kalpaklioglu, AF; Baccioglu, A; Yalim, SA; Yilmaz, I; Kalkan, IK; Uysal, MA; Niksarlioglu, EY; Kalyoncu, AF; Karakaya, G; Erbay, M; Nayci, S; Tepetam, FM; Gelincik, AA; Dirol, H; Goksel, O; Karaoglanoglu, S; Erkekol, FO; Isik, SR; Yildiz, F; Yavuz, Y; Karadogan, D; Bozkurt, N; Seker, U; Oguzulgen, IK; Basyigit, I; Baris, SA; Ucar, EY; Erdogan, T; Polatli, M; Ediger, D; Gunaydin, FE; Turk, M; Pur, L; Katran, ZY; Sekibag, Y; Aykac, EF; Mungan, D; Gul, O; Cengiz, A; Akkurt, B; Ozden, S; Demir, S; Unal, D; Aslan, AF; Can, A; Gumusburun, R; Bogatekin, G; Akten, HS; Inan, S; Erdinc, M; Ogus, AC; Kavas, M; Yulug, DP; Cakmak, ME; Kaya, SB; Alpagat, G; Ozgur, ES; Uzun, O; Gulen, ST; Pekbak, G; Kizilirmak, D; Havlucu, Y; Donmez, H; Arslan, B; Cetin, GP; Soyyigit, S; Kara, BY; Karakis, GP; Dursun, AB; Kendirlinan, R; Ozturk, AB; Sevinc, C; Simsek, GO; Abadoglu, O; Cerci, P; Yucel, T; Yorulmaz, I; Tezcaner, ZC; Tatar, EC; Suslu, AE; Ozer, S; Dursun, E; Yorgancioglu, AIntroductionNational data on asthma characteristics and the factors associated with uncontrolled asthma seem to be necessary for every country. For this purpose, we developed the Turkish Adult Asthma Registry for patients with asthma aiming to take a snapshot of our patients, thereby assigning the unmet needs and niche areas of intervention.MethodsCase entries were performed between March 2018 and March 2022. A web-based application was used to record data. Study outcomes were demographic features, disease characteristics, asthma control levels, and phenotypes.ResultsThe registry included 2053 patients from 36 study centers in Turkey. Female subjects dominated the group (n = 1535, 74.8%). The majority of the patients had allergic (n = 1158, 65.3%) and eosinophilic (n = 1174, 57.2%) asthma. Six hundred nineteen (32.2%) of the patients had obese asthma. Severe asthma existed in 670 (32.6%) patients. Majority of cases were on step 3-5 treatment (n: 1525; 88.1%). Uncontrolled asthma was associated with low educational level, severe asthma attacks in the last year, low FEV1, existence of chronic rhinosinusitis and living in particular regions.ConclusionThe picture of this registry showed a dominancy of middle-aged obese women with moderate-to-severe asthma. We also determined particular strategic targets such as low educational level, severe asthma attacks, low FEV1, and chronic rhinosinusitis to decrease uncontrolled asthma in our country. Moreover, some regional strategies may also be needed as uncontrolled asthma is higher in certain regions. We believe that these data will guide authorities to reestablish national asthma programs to improve asthma service delivery.Item Trends in prescribing montelukast in patients with asthma in real-life: Results from the Turkish adult asthma registryBeyaz, S; Erdinç, M; Hayme, S; Aslan, AF; Aydin,Ö; Gökmen, D; Buhari, GK; Sözener, ZC; Gemicioglu, B; Bulut, I; Örçen, C; Özdemir, SK; Keren, M; Damadoglu, E; Yakut, T; Kalpaklioglu, AF; Baccioglu, A; Yalim, SA; Yilmaz, I; Kalkan, IK; Uysal, MA; Niksarlioglu, EYÖ; Kalyoncu, AF; Karakaya, G; Erbay, M; Nayci, S; Tepetam, FM; Gelincik, AA; Dirol, H; Göksel,Ö; Karaoglanoglu, S; Erkekol, FÖ; Isik, SR; Yildiz, F; Yavuz, Y; Karadogan, D; Bozkurt, N; Seker,Ü; Oguzülgen, IK; Basyigit, I; Baris, SA; Uçar, EY; Erdogan, T; Polatli, M; Ediger, D; Günaydin, FE; Türk, M; Pür, L; Katran, ZY; Sekibag, Y; Aykaç, EF; Mungan, D; Gül,Ö; Cengiz, A; Akkurt, B; Özden, S; Demir, S; Ünal, D; Can, A; Guemuesburun, R; Bogatekin, G; Akten, HS; Inan, S; Ögüs, AC; Kavas, M; Yulug, DP; Çakmak, ME; Kaya, SB; Alpagat, G; Özgür, ES; Uzun, O; Gülen, ST; Pekbak, G; Kizilirmak, D; Havlucu, Y; Doenmez, H; Arslan, B; Çetin, GP; Soyyigit, S; Kara, BY; Karakis, GP; Dursun, AB; Kendirlinan, R; Öztürk, AB; Sevinç, C; Simsek, GÖ; Abadoglu,Ö; Çerçi, P; Yücel, T; Yorulmaz, I; Tezcaner, ZÇ; Tatar, EÇ; Süslü, AE; Özer, S; Dursun, E; Yorgancioglu, A; Çelik, GEMontelukast, a leukotriene receptor antagonist (LTRA) approved for the treatment of asthma and allergic rhinitis, is widely used, though real-world data on its application in asthma management remain limited. This registry-based study evaluated the use of montelukast in adult asthma patients, examining demographic and disease characteristics, asthma control status, asthma phenotypes, presence of atopy, and treatment regimens. Among 2053 patients analyzed, 61.76% (n = 1268; mean age: 46.2 +/- 14.3 years), predominantly females (similar to 76%), received montelukast. Montelukast users showed higher rates of allergic rhinitis (P < 0.001), hypersensitivity to nonsteroidal anti-inflammatory drugs (NSAIDs) (P = 0.008), and chronic rhinosinusitis (P = 0.008). Montelukast group also had higher atopy and total IgE levels and tended to be more eosinophilic. Montelukast was commonly preferred in allergic, eosinophilic, NSAID-exacerbated respiratory disease, and severe asthma phenotypes (P < 0.001). Patients receiving Steps 4 and 5 treatments are more likely to be prescribed montelukast (P < 0.001). Montelukast usage was higher among patients with uncontrolled asthma [ACT< 20 (OR:1.29, 95%CI:1.052-1.582, P = 0.014)]. In addition, logistic regression analyses identified the main factors associated with increased montelukast use as; female gender (OR:1.33, 95%CI:1.041-1.713, P = 0.02), presence of atopy (OR:1.46, 95%CI:1.157-1.864, P = 0.002), comorbid allergic rhinitis (OR:2.12, 95%CI:1.679-2.293, P < 0.001), and severe asthma (OR:2.18, 95%CI:1.712-2.784, P < 0.001). These findings reveal that montelukast use is prevalent among asthma patients, particularly in females, middle-aged adults, and those with comorbid allergic rhinitis, uncontrolled asthma, or specific asthma phenotypes, underscoring the factors that influence its prescription in asthma management.

This study aims to analyze the factors related to the prescription of add-on LAMA in clinical practice for asthma patients, shedding light on physicians' preferences. This study included adult asthma patients on add-on LAMA and ICS/LABA monitored for at least one year in a national registry comprising 2053 asthmatics. Patients' characteristics and disease profiles were analyzed to identify factors associated with the prescription of add-on LAMA across the entire cohort. A comparative analysis was performed among three groups: MART (ICS/formoterol as a maintenance and reliever therapy) plus LAMA, Conventional (ICS/LABA as a maintenance and short-acting beta agonist as reliever) plus LAMA and Triple (ICS/ LABA/LAMA single inhaler). LAMAs were added to ICS/LABA in 11.7 % of patients in the national registry. Logistic regression analysis revealed that older age, low FEV1 (%), Asthma Control Test (ACT) scores less than 20, and severe exacerbation were the main factors influencing the initiation of LAMA in our registry. However, demographic characteristics of asthma, control status, pulmonary function test results were similar among the three groups of LAMA users (p > 0.05). Physicians used LAMAs without phenotyping based on allergic status or eosinophil levels (p > 0.05). Mepolizumab was added after LAMA in all patients, while omalizumab was initiated before LAMA in 16.9 % of the patients receiving LAMA along with biologics. Add-on LAMAs were predominantly prescribed for older, uncontrolled, and exacerbated asthma patients with low FEV1.Item Prevalence and Risk Factors of Allergies in Turkey (PARFAIT): results of a multicentre cross-sectional study in adultsKurt, E; Metintas, S; Basyigit, I; Bulut, I; Coskun, E; Dabak, S; Deveci, F; Fidan, F; Kaynar, H; Uzaslan, EK; Onbasi, K; Ozkurt, S; Karakis, GP; Sahan, S; Sahin, U; Oguzulgen, K; Yildiz, F; Mungan, D; Yorgancioglu, A; Gemicioglu, B; Kalyoncu, AFThe Prevalence and Risk Factors of Allergies in Turkey (PARFAIT) study was planned to evaluate the prevalence of and risk factors for asthma and allergic diseases in Turkey. The present analysis used data from 25,843 parents of primary school children, obtained from a cross-sectional questionnaire-based study. A total of 25,843 questionnaires from 14 centres were evaluated. In rural areas, the prevalences asthma, wheezing, allergic rhinitis and eczema in males were: 8.5% (95% confidence interval (CI) 7.9-9.1%), 13.5% (95% Cl 12.8-14.2%), 17.5% (95% Cl 16.7-18.2%) and 10.8% (95% Cl 10.2-11.4%), respectively; and in females were: 11.2% (95% Cl 10.9-11.8%), 14.7% (95% Cl 14.3-15.1%), 21.2% (95% Cl 20.4-22.0%) and 13.1% (95% Cl 12.4-13.8%), respectively. In urban areas, the corresponding prevalences in males were: 6.2% (95% Cl 5.8-6.6%), 10.8% (95% Cl 10.3-11.3%), 11.7% (95% Cl 11.4-12.0%) and 6.6% (95% Cl 6.2-7.0%), respectively; and in females were: 7.5% (95% Cl 7.9-7.1%), 12.0% (95% Cl 11.7-12.3%), 17.0% (95% Cl 16.4-17.6%) and 7.3% (95% Cl 6.9-7.7%), respectively. Having an atopic first-degree relative or any other atopic diseases had significant effects on the prevalence of allergic diseases. Housing conditions, such as living in a shanty-type house, visible moulds at home and use of wood or biomass as heating or cooking material were associated with one or more allergic diseases. Although genetic susceptibility is strongly associated, country- and population-based environmental factors may contribute to increased prevalence rates of allergic diseases.Item Prevalence and risk factors of allergies in Turkey: Results of a multicentric cross-sectional study in childrenKurt, E; Metintas, S; Basyigit, I; Bulut, I; Coskun, E; Dabak, S; Deveci, F; Fidan, F; Kaynar, H; Uzaslan, EK; Onbasi, K; Ozkurt, S; Pasaoglu, G; Sahan, S; Sahin, U; Oguzulgen, K; Yildiz, F; Mungan, D; Yorgancioglu, A; Gemicioglu, B; Kalyoncu, AFThe Prevalence And Risk Factors of Allergies in Turkey (PARFAIT) study was planned to evaluate prevalence and risk factors of asthma and allergic diseases and also to find out which geographical variables and/or climatic conditions play a role determining the prevalence of allergic diseases in Turkish school children. Study was planned as cross-sectional questionnaire-based. About 25,843 questionnaires from 14 centers were appropriate for analysis. Parental history of allergy, having an atopic sibling and other atopic disease in index case was significant risk factors for all allergic diseases. Breast feeding decreased the risk of current asthma (OR: 0.92, CI: 0.86-0.99) and wheezing (OR: 0.93, CI: 0.87-0.99) but not allergic rhinitis and eczema. Respiratory infection in the past was an important risk factor for the occurrence of allergic diseases especially for asthma which was increased 4.53-fold. Children exposed to household smoke were significantly at higher risk of asthma, wheezing, and allergic rhinitis (OR: 1.20, CI: 1.08-1.33; OR: 1.21, CI: 1.09-1.34; and OR: 1.32, CI: 1.21-1.43, respectively). All allergic diseases were increased in those children living in areas which have altitude of below 1000 m and mean yearly atmospheric pressure above 1000 mb. The study has suggested that household and country-specific environmental factors are associated with asthma, wheezing, allergic rhinitis, and eczema risk during childhood in Turkey.Item Push and Pull Factors of Why Medical Students Want to Leave Turkiye: A Countrywide Multicenter StudyEser, E; Cil, E; Sen Gundogan, NE; Col, M; Ozturk, ENY; Thomas, DT; Sunter, AT; Arslan, HN; Citil, R; Onder, Y; Picakciefe, M; Dede, B; Demirel, C; Aydin, N; Caglayan, C; Aker, AA; Borlu, A; Durmus, H; Can, G; Siddikoglu, E; Sumer, EH; Uygun, T; Alkoy, S; Aycan, KA; Koruk, I; Kuzan, R; Demir, LS; Hacilar, E; Sari, H; Kilinc, Z; Onal, O; Dogan, E; Emek, M; Terzioglu, R; Yapici, G; Erdal, D; Eser, S; Akman, EA; Kosan, Z; Yilmaz, S; Ayoglu, FN; Acikgoz, B; Musal, B; Suner, AF; Erdogan, A; Cilburunoglu, I; Saygun, M; Daymaz, D; Arslantas, D; Onsuz, MF; Beyhun, NE; Ustundag, MG; Ekuklu, G; Tas, FO; Abacigil, F; Oncu, S; Hidiroglu, S; Ozaydin, AN; Pirincci, E; Bulut, I; Tozun, M; Eskiocak, M; Gunel, P; Torun, SD; Yavuz, M; Hasde, M; Camur, D; Gunes, G; Kurt, B; Baysoy, NG; Bakirci, N; Demir, F; Catak, B; Ozyurda, F; Turan, MPhenomenon: Physician immigration from other countries is increasing as developed countries continue to be desirable destinations for physicians; however, the determinants of Turkish physicians' migration decisions are still unclear. Despite its wide coverage in the media and among physicians in Turkiye, and being the subject of much debate, there is insufficient data to justify this attention. With this study, we aimed to investigate the tendency of senior medical students in Turkiye to pursue their professional careers abroad and its related factors. Approach: This cross-sectional study involved 9881 senior medical students from 39 different medical schools in Turkiye in 2022. Besides participants' migration decision, we evaluated the push and pull factors related to working, social environment and lifestyle in Turkiye and abroad, medical school education inadequacy, and personal insufficiencies, as well as the socioeconomic variables that may affect the decision to migrate abroad. The analyses were carried out with a participation rate of at least 50%. Findings: Of the medical students, 70.7% had emigration intentions. Approximately 60% of those want to stay abroad permanently, and 61.5% of them took initiatives such as learning a foreign language abroad (54.5%) and taking relevant exams (18.9%). Those who wanted to work in the field of Research & Development were 1.37 (95% CI: 1.22-1.54) times more likely to emigrate. The push factor that was related to emigration intention was the working conditions in the country (OR: 1.89, 95% CI: 1.56-2.28) whereas the social environment/lifestyle abroad was the mere pull factor for the tendency of emigration (OR: 1.73, 95% CI: 1.45-2.06). In addition, the quality problem in medical schools also had a significant impact on students' decisions (OR: 2.20, 95% CI: 1.83-2.65). Insights: Although the percentage of those who want to emigrate definitely was at the same level as in the other developing countries, the tendency to migrate permanently was higher in Turkiye. Improving working conditions in the country and increasing the quality of medical faculties seem vital in preventing the migration of physicians.Item Push and Pull Factors of Why Medical Students Want to Leave Türkiye: A Countrywide Multicenter StudyEser, E; Cil, E; Sen Gundogan, NE; Col, M; Ozturk, ENY; Thomas, DT; Sunter, AT; Arslan, HN; Citil, R; Onder, Y; Picakciefe, M; Dede, B; Demirel, C; Aydin, N; Caglayan, C; Aker, AA; Borlu, A; Durmus, H; Can, G; Siddikoglu, E; Sumer, EH; Uygun, T; Alkoy, S; Aycan, KA; Koruk, I; Kuzan, R; Demir, LS; Hacilar, E; Sari, H; Kilinc, Z; Onal, O; Dogan, E; Emek, M; Terzioglu, R; Yapici, G; Erdal, D; Eser, S; Akman, EA; Kosan, Z; Yilmaz, S; Ayoglu, FN; Acikgoz, B; Musal, B; Suner, AF; Erdogan, A; Cilburunoglu, I; Saygun, M; Daymaz, D; Arslantas, D; Onsuz, MF; Beyhun, NE; Ustundag, MG; Ekuklu, G; Tas, FO; Abacigil, F; Oncu, S; Hidiroglu, S; Ozaydin, AN; Pirincci, E; Bulut, I; Tozun, M; Eskiocak, M; Gunel, P; Torun, SD; Yavuz, M; Hasde, M; Camur, D; Gunes, G; Kurt, B; Baysoy, NG; Bakirci, N; Demir, F; Catak, B; Ozyurda, F; Turan, MPhenomenon: Physician immigration from other countries is increasing as developed countries continue to be desirable destinations for physicians; however, the determinants of Turkish physicians' migration decisions are still unclear.

We aimed to assess the differences between obese and non-obese patients with asthma. Methods: This research is a subanalysis of the Turkish Adult Asthma Registry (TAAR). Clinical presentation, disease control, severity, and demographics of obese and non-obese (normal-weight, overweight) patients were compared. Results: The obesity rate in TAAR was 32.2% (n=619/1919; 18-83years; 527F/92 M). Patients with asthma and obesity had higher rates of childhood obesity, longer symptom duration, later onset of asthma, and more severe asthma. These patients were more likely to be female, older, less educated, and live in rural areas. Patients with obesity had more scheduled visits and emergency visits compared with non-obese patients, but similar asthma control, oral corticosteroid use, hospitalizations, intensive care unit admissions, and unscheduled visits. They also had a higher frequency of T2-high but lower frequency of possible T2-low phenotypes compared with normal-weight asthmatics. The risk of severe asthma in patients with obesity was 6.04 times higher for allergic than non-allergic patients and 3.58 times higher for the T2-high phenotype than for possible T2-low phenotypes. A one-unit increase in the asthma control test reduced the risk of severe asthma by 22%. Conclusions: A good definition of this phenotype is important to ensure that appropriate treatment strategies are implemented to achieve the control goal. We also believe that prevention of childhood obesity is an effective and pivotal strategy to achieve the goal of asthma control.
