Introduction: Bronchiectasis is a chronic progressive respiratory disease characterized by permanent dilatation of the bronchi. It is a complex condition with numerous different etiologies, co-morbidities, and a heterogeneous presentation. As we know, there is a lack of studies that describe the differences and compare the characteristics between focal and multifocal bronchiectasis. The aim of this study is to identify differences in clinical characteristics presentation, severity or distribution in focal and multifocal bronchiectasis, and prognostic implications. Methods: 126 patients with computed tomography (CT)-verified bronchiectasis were enrolled. Baseline characteristics that included age, sex, smoking history, and respiratory symptoms were recorded, with special attention paid to hemoptysis appearance, body mass index, and comorbidities. The type of bronchiectasis determined by CT scan and the modified Reiff scores indicating radiological severity were recorded. Patients were divided in two groups (I is focal and II is multifocal). Results: There were no statistically significant differences in age, smoking status, comorbidity, and BMI between the two groups. Multifocality was associated with a significantly higher proportion of females (p = 0.014), the rate of hemoptysis (p = 0.023), and the number of hospitalizations, but not of exacerbations and prevalence of immunodeficiency (p = 0.049). Significantly, a high number of subjects with multifocality had bronchiectasis of moderate severity, and post-infective and asthma-associated phenotypes were the dominant in this group. Unexpectedly, the cystic and varicose radiological phenotype (which need more time to develop) were more dominant in the focal group. The cylindrical phenotype was equally observed in the multifocal and focal groups. Conclusions: Our study suggests that multifocality is not related to age, number of exacerbations, or radiological phenotype, but it seems to be associated with the clinical post-infective phenotype, immunodeficiency, frequent hospitalizations, and severity. Thus, the presence of multifocal bronchiectasis may act as a biomarker of severity and poor outcomes in these patients.

Three subtypes of achalasia have been defined using esophageal manometry. Several studies have reported that symptoms are experienced differently among men and women, regardless of subtype. All subtypes could have some impact on the appearance of respiratory symptoms and lung complications due to compression of the trachea or aspiration of undigested food. The aim of this research was to analyze the differences in respiratory symptoms and radiographic presentation of lung pathology depending on the diameter and achalasia types. One or more respiratory symptoms were reported in 48% of 114 patients, and all of them had two or more gastrointestinal symptoms. The symptom score (SS) is statistically significant for the prediction of subtype 1 (area under the curve = 0.318; p < 0.001, cut-off score of 6.5 had 95.2% sensitivity) and subtype 2 (area under the curve = 0.626; p = 0.020, cut-off score of 7.5 had 93.1% sensitivity). The most common type was subtype 2 (50.8%), and although only 14 patients had subtype 3, they had the largest esophageal diameter (mean 5.8 cm). The difference in esophageal diameter was significant between subtype 1 and 3 (p = 0.011), subtype 2 and subtype 3 (p = 0.011). Nine patients (6%) had mega-esophagus (four patients in type 1, three in type 2 and two in type 3). More than half of all patients (51.7%) had at least one parenchymal lung change on CT scan. Recurrent micro-aspirations led to changes in the structure of the airways and lung parenchyma such as ground glass (GGO) and nodular changes (12%) and fibrosis (14.5%), and they had higher esophageal diameters (p < 0.001). Patients with chronic lung CT changes had significantly higher esophageal diameter than with acute changes (p < 0.001). Awareness of the association of achalasia and lung disorders is important in early diagnosis and treatment. More than half (57.5%) of patients with achalasia had some clinical and/or structural pulmonary abnormalities. All three subtypes had similar respiratory symptoms, meaning they cannot be used to predict the subtype of achalasia; on the contrary, SS can predict the first two subtypes. A higher diameter of the esophagus is associated with chronic structural lung changes. Although unexpected, the pathological radiological findings and diameter were significantly different in subtype 3 patients, but those parameters cannot lead us to a specified subtype.

Sarcoidosis is a granulomatous disease of unknown etiology that can affect almost any organ. Although the acute form can have spontaneous regression, a certain number of patients can have a chronic form, which leads to an increase in mortality and a decrease in the quality of life. Considering that the risk factors are still unknown, we wanted to compare the characteristics of patients with acute and chronic forms of sarcoidosis in Serbia in order to determine significant differences between them with hopes of contributing to everyday clinical practice. A total of 2380 patients treated in our clinic were enrolled in this study. They were separated into the following two groups: 1126 patients with acute form and 1254 patients with chronic form. They were further compared by gender, smoking status, radiological status, exposition, biomarkers for sarcoidosis, organ involvement, and other comorbidities; the distribution of patients according to regions of Serbia was also noted. Statistical significance was found in radiological findings (p < 0.001), biomarkers (calcium in 24 h urine p < 0.001; chitotriosidase p = 0.001), and the affliction of organs (p < 0.001). The differences noted in this paper could help improve our understanding of this disease.

Background and Objectives: Acute pulmonary thromboembolism (PTE) is one of the leading causes of cardiovascular mortality. Recent insights into PTE pathophysiology emphasize the complex interplay of multiple mechanisms, particularly the roles of thrombosis and inflammation. Materials and Methods: This retrospective, single-center observational study included 138 participants: 69 adult patients diagnosed with PTE via computed tomography pulmonary angiography (CTPA) and 69 matched healthy controls. Upon admission, a standard 12-lead electrocardiogram (ECG) was performed, and Daniel’s score was calculated. Peripheral blood samples were collected to assess inflammatory biomarkers and hemogram-derived ratios (SII, NLR, dNLR, NPR, PLR, LMR). CTPA scans were analyzed not only for diagnostic purposes and PTE localization but also for inflammatory changes. PTE severity was classified according to the 2019 ESC guidelines. Results: Patients with PTE had significantly higher Daniel’s ECG scores, initial values of inflammatory biomarkers (WBC, neutrophils, IL-6, CRP) and hemogram-derived ratios (SII, NLR, dNLR, NPR) compared to controls. In multivariate analysis, older age (OR = 1.05; p = 0.038), higher Daniel’s ECG score (OR = 1.24; p < 0.001), and higher dNLR (OR = 1.40; p = 0.001) were found as an independent predictors of PTE severity. Ground-glass opacity (GGO) was the most common parenchymal and pleural inflammatory finding relating to CTPA (48.4%), but these findings did not show significant predictive value for PTE severity. Conclusions: Daniel’s ECG score and dNLR, both readily available and cost-effective biomarkers demonstrated independent predictive value for assessing PTE severity.
