Article Impact of Inspiratory Muscle Strength and Lung Function on Functional Exercise Capacity in Post-Myocardial Infarction Patients: A Cross-Sectional Study(Galenos Publishing House, 2025-09-18) Aktan, Rıdvan; Ozalevli, Sevgi; Dursun, Huseyin; Aktan, Özge Ocaker; Ocaker Aktan, OzgeOBJECTIVE: This study aims to investigate the contribution of lung function and respiratory muscle strength in predicting functional exercise capacity in post-myocardial infarction (MI) subjects. MATERIAL AND METHODS: This cross-sectional study included 56 stable post-MI subjects. Lung function was assessed using a digital spirometer, and respiratory muscle strength was measured using an intraoral pressure meter. The 6-minute walk distance (6MWD) was conducted to assess functional exercise capacity. Correlations and multiple regression analyses were performed to evaluate predictors of 6MWD, considering demographic factors, lung function, and respiratory muscle strength. The Bland-Altman plot was used to investigate the agreement between observed and predicted 6MWDs. RESULTS: Significant positive correlations were found between 6MWD and forced vital capacity (FVC)%predicted (r = 0.528, P = 0.022) and maximum inspiratory pressure (MIP)%predicted (r = 0.640, P = 0.022). Age (r = -0.350, P = 0.008) and body mass index (BMI) (r= -0.561, P < 0.001) were negatively correlated with 6MWD. The best regression model included MIP%predicted (β = 0.332, P = 0.002), BMI (β = -0.264, P = 0.012), being male (β = 0.262, P = 0.003), age (β = -0.210, P = 0.020), and FVC%predicted (β = 0.219, P = 0.026) as significant unique contributors. The final multiple linear regression model was significant [F (5, 50) = 19.08, P < 0.001] and explained 65.6% of the variance (R2 = 0.656) in the 6MWD. CONCLUSION: Lung function and respiratory muscle strength significantly contribute to functional exercise capacity in post-MI. This study emphasizes the importance of comprehensive respiratory function assessments in rehabilitation strategies to improve exercise capacity in patients with post-MI.Letter Citation - WoS: 1Citation - Scopus: 1About The Article Titled “a Different Scintigraphic Perspective On The Systolic Function Of The Left Ventricle-1” [“sol Ventrikül Sistolik Fonksiyonuna Sintigrafik Olarak Farklı Bir Bakış Açısı-1” Başlıklı Makale Hakkında](Galenos Publishing House, 2024-02-23) Taşçı, Cengiz; Tascs, Cengiz[No abstract available]Article Hypermetabolic Axillary Lymph Nodes Associated With Covid-19 Vaccination in Breast Cancer Management(Galenos Publishing House, 2023-06-01) Taşçı, Cengiz; Dirican, Ahmet; Sözbilen, Ethem Murat; Pehlivan, F.S.; Serter, SelimA 42-year-old female patient diagnosed with invasive ductal breast ca underwent18F-fluorodeoxyglucose (FDG) positron emission tomography/ computed tomography (PET/CT) scan for staging, 1.5 cm diameter hypermetabolic lesion was observed in the lower inner quadrant of the right breast that was compatible with primary tumor [maximum standardized uptake value (SUVmax ): 10.5]. No pathological18F-FDG uptake was observed in lymph nodes whose fatty hilum was seen in the right axilla. However, in the left axilla and left deep axilla, hypermetabolic lymph nodes with a maksimum diameter of 19 mm and fatty hilum were observed (SUVmax: 8.0). In a detailed CT evaluation, these lymph nodes have thicker walls than the ones in the right axilla. The patient was questioned again and coronavirus disease-2019 (COVID-19) vaccination history (with BNT162b2, COVID-19 mRNA vaccine) was determined that was administrated to the left arm 5 days ago. Tru-cut biopsy was performed from the left aksillary lymph nodes and proved to be reactive lymphoid tissue and there was no primary or metastatic tumor in these axillary lymph node tissues. The patient was given neoadjuvant chemotherapy 4.5 months after the first18F-FDG PET/CT, and the second was performed for the treatment response evaluation. Significant regression was determined from the findings. The patient underwent right total mastechtomy. She was being followed up with adjuvant chemotherapy and radiotherapy. In conclusion, hypermetabolic lymph nodes in the axillas should be interrogated for vaccination in patients with breast cancer. Hypermetabolic lymph nodes observed on the same side of the vaccinated arm in the 18 F-FDG PET/CT scan may be related to vaccine-induced reactive lymph node enlargement. Lymph node metastasis may be excluded, especially if there are hypermetabolic lymph nodes with preserved fatty hilum in the contralateral axilla on the same side as the vaccinated arm. Active lymph nodes reactive to the vaccine become inactive after a while. © 2023 by the Turkish Society of Nuclear Medicine.
